[Serious] What's the cruelest thing you have ever done to somebody?

I did some terrible shit with a girls laundry in college that I'm not proud of but fuck it and that girl. My girlfriend lived in a school owned house with about 10 other dorm rooms in it at college and they had a washer and dryer in the basement which were first come first serve. Well one afternoon someone took all my girlfriends cloths out mid wash, they still had soap on them and didn't even get to the rinse cycle. It's not like she left them in there after they were done, she was actively using the washer and nobody had any cloths or anything down there showing they where about to use it before she claimed it. Well it ruined 2 of her shirts which was maybe $40 worth of cloths so I took her to my home (lived about 10 min away in my own place) to let her use my washer and dryer. I ordered a pizza for us for dinner as she was upset about it. Now she was cooling off but I was apocalypticly angry. So when I went to get the pizza I grabbed her keys and went back to see if I could confront this bitch. I waited for like 15 minutes in the basement for this girl to show up so I could tear her a new one and demand $$ but she never did and I had to actual pick up that pizza. So in a moment of stupidity and anger, I grabbed a quart of light grey rustoleum oil based paint out of my truck (was working part time doing home construction), I popped the top off, chucked it in the washer with this girls cloths and put it on an extra rinse cycle. I instantly knew I'd gone WAY too far but, I do take some solice in knowing I ruined an entire load of that girls clothing. I also found out I ruined the washer. My girlfriend knew enough to keep her mouth shut when campus security came around (as it was vandalism) and she never asked if it was me that did it but I assume she had to know. To preemptively answer some questions...yes I know it was super shitty to do even given the situation, no I don't really care. My GF couldn't regularly use my washer/dryer as she didn't have her own car to get to me and with how busy we both where we often didn't see each other for a few days at a time. Also I was the only name on my lease and having her over every night would violate my lease agreement. Never found out how that girl reacted or even who she was. Campus security talked with the RA and the RA told the girls in that house what happened and asked around but no one came forward.
