We are not all model citizens – in fact, few of us are. Most of us have done things we regret because they hurt others, whether accidentally or otherwise. But even knowing that an action is bad is not always enough to stop us from doing it. You can find plenty of reasons to justify hurting others if you really want to. Good reasons? Maybe not. But that didn’t stop these 20 AskReddit users, whose confessions were collected from across the forum. Some of these people could use some serious help:

1. Just a little pencil mark…

There was once this kid who used to give me a hard time on the bus when I was in High School. even as seniors he never let up on me for some reason. He was in my english class and was barely passing with D’s. One day he squirted an entire bottle of ketchup in my locker and all over my new Nike jacket my mom had gotten me. We didn’t have money for brand name things so this jacket was big deal to me. He completely ruined it. Well towards the end of our senior year, I volunteered to help out as a sound tech for the school play.

Our English teacher was also the drama teacher and she would let the sound people use her classroom to keep our stuff in. I found myself alone in her class one night during practice and noticed her grade book opened with our english class grades in front of me. She actually wrote everything in her grade book in pencil. So I quickly grabbed a pencil and changed some of his grades. A month later, he failed that class (barely) and didn’t graduate with our class. He had to go back the next year and graduate a year later. It was quite the shock of our little town b/c he was a very popular boy from a very popular family. I still don’t feel bad about it but I realize it was evil.

2. All of this is fucked up.

My old roommate used to get mad and hit me when things didn’t go his way or got drunk, so I did the unforgivable… He was a black guy and had bottles of Lubriderm lotion laying around for his ashy skin. He used to rub it all over his body and face. I kept thinking of ways to get revenge and it randomly came to me. I masturbated into a cup and poured it into the bottle of lotion… A day later he comes out of his room with his shirt off, acting like a douche bag and begins rubbing the lotion on his chest and face… I couldn’t contain myself. My other roommate told me, that he in fact, did the same thing after I told him of my fiasco.

3. It really is a cycle

There was a kid who lived in the house whos back yard butted up against my grandparents. This kid was the type who would play with you no matter wtf evil shit you did to him. I guess it was my own ego looking for an outlet since I was pretty picked on growing up. This kid wanted to play with me and my cousin. We let him come over to my grandparents back yard. We played cowboys and indians. Me and my cousin tied the kid to a pole near the swing set, pantsed him, and went inside to watch TV. I don’t remember how long it was but his father came home only to see his son tied to a pole with his pants at his ankles. I got my ass whipped for it by my grandfather. I still feel bad about it to this day.

4. Maxi Pad

In grade 7 I knew a guys gym locker combination, I took a sample maxi pad that came in the mail and put it in there. While he was getting changed for gym class it fell on the floor. Other students proceeded to kick it out of the locker room and around the gymnasium floor, all the while making fun of him for being a girl. He didn’t come back the next day and never returned. I’m not sure if it was related or not but I feel a bit guilty.

5. So…you were just a little shit

Blamed kid down the street for breaking a window I broke at my house. Kid got a beating for it. So did I when it was discovered that I lied. (~6yo)
Flattened every tire on some guys raised pick-up (with giant tires) by unscrewing the pin in the valve. Woke up the next morning to see his car on blocks — He had taken the tires to the shop. (~11yo)
Shot kids (when I was 11yo) with blow darts made from straws and cactus thorns. We also told them the tips had been dipped in black widow poison.
Accidentally broke someones arm after I intentionally pushed him into a wall while we were chasing a ball in gym class. (13yo).
Threw full 7-11 cup of Dr. Pepper over the top of stall onto some unsuspecting guy taking a shit. (~16yo)
Filled a bucket of every rotten old food and drink in my college fridge (plus several bottles of cologne and about 30 slugs), let it sit in the sun for about 2 weeks until it became a loaf, rehydrated it with rotten milk and beer, filled plastic bags full of the material, then drove around looking for people to hit with the dank. At least 4 people had direct hits scored on them. This stuff was awful smelling. Really awful. I still feel tremendous guilt over this one. (~19yo) Note: With the exception of the first one, the rest were the result of bad influences. That doesn’t excuse it, I know.

6. That’s like straight out of a movie or something

In third grade, I cheated on my history exam. In fourth grade, I stole my uncle Max’s toupee and I glued it on my face when I was Moses in my Hebrew School play. In fifth grade, I knocked my sister Edie down the stairs and I blamed it on the dog…When my mom sent me to the summer camp for fat kids and then they served lunch I got nuts and I pigged out and they kicked me out…But the worst thing I ever done — I mixed a pot of fake puke at home and then I went to this movie theater, hid the puke in my jacket, climbed up to the balcony and then, t-t-then, I made a noise like this: hua-hua-hua-huaaaaaaa — and then I dumped it over the side, all over the people in the audience. And then, this was horrible, all the people started getting sick and throwing up all over each other. I never felt so bad in my entire life.

7. The thought process here…why?

Live in a small vacation town that’s quite abandoned in the off season. One particular morning, while waiting for the bus, I decided that I would skip a fine opportunity to attend school. Since my Dad started work in over an hour, I couldn’t go home after skipping, so instead I went up the block and strolled about town. Once I had traveled a couple blocks of eerily silent shore town, I found the nicest outdoor shower I came across, one with a bench, and hung out inside it smoking a few joints (back then I stocked my wallet like a portable smoking kit).

Now, before I go to the bus stop, I’ll usually make sure to drop a load, since my bus ride was around 45 minutes long. This particular morning I neglected to do so, and paid the price accordingly. Waiting for my father to leave for work had me pushing well beyond my shit-withholding threshold, and I was cold and high. The solution came easily enough in the form of an unlocked door behind what I assume to be a family’s winter home and summer-rental. I’m sure it was seasonal as the house itself was abandoned, and the unlocked door led me into a small, 4×6 ft laundry room, something of a rarity. Doing the logical thing I searched my backpack for tissues, found some, and dropped my pants thusly, before jumping onto the washing machine and dispensing into it a really nice shit. When I say nice shit, it comes from the heart. You know those rare, amazing shits where it slides right out, intact and large? And then the feeling of success after having wiped your ass and finding that the toilet paper, or in this case tissue, has almost nothing on it? So I shit in the random house’s washing machine, and nearly thirty seconds later was gagging at the smell that accumulated in such a small space, something I never anticipated. Being that this was a seasonal residence, I consider the occupants lucky, as, for most people the shit would have lingered, slowly building it’s lethality, for months.

I was pleasantly surprised a week after my deed. While walking to the beach to smoke a blunt, I saw a bald middle aged man with a scowl hosing out the room I was so recently defecating in. Interesting to note was the large amount of children’s toys in their yard. I imagine the family happily pulling up in the driveway, ready to enjoy a weekend away from it all, and then the expression on the face of the little girl who discovered my joyful shit. I like to think she looks like Dora the Explorer in real life.
I feel the most evil part of this is that it would’ve actually been a shorter trip were I to shit on the beach and bury it.

8. …WTF?!

Introduced Yeast Infections to both of my female house mates as punishment for not paying rent on time…

9. “I think he kind of appreciated it”

One of my friends in High School had cancer, it was the really bad kind and he had been fighting it pretty much his entire life most of the time the doctors kept telling his mom that he would not make it.

I treated him like shit, everyone else was incredibly nice to him because of the cancer but i always acted like he was an annoying little bother. The funny thing is, I think he kind of appreciated it, I was the only person in his life outside of his family who did not pity him.

He was so pathetic, even when the doctors told him he had finally beat the cancer he had no clue what to do with his life, he spent so long assuming he would die before turning 18 that he had absolutely no ambition other than playing games on the computer he got from the make a wish foundation.

He died a few months after turning 18, I was studying abroad but my parents told me he tried calling me a week before he died even though he knew i was not there.

I feel like the lowest form of scum on earth for the way i treated him, still have not been able to bring myself to visit his grave to apologize, maybe some day.

I am truly sorry Dave, i should of been a better friend to you.

10. Responsible

I bullied someone who later killed themselves. I’ve never known the reason why she killed herself, but there is always that thought in the back of my head that makes me think I was responsible.
