TASK DEFINITION: Given a real-life anecdote of a complex ethical situation, identify who is wrong here. Classify each post into the following categories : AUTHOR (if the author of the post is wrong in the situation), OTHER (if any of the others mentioned in the paragraph is wrong), EVERYBODY (if everyone mentioned is wrong) and NOBODY (if no one is wrong in the situation).
PROBLEM: So this happened exactly a week ago. I brought my new girlfriend to my parents house to meet my family. I introduced her to everyone and everyone was pretty nice except my sister. She’s not the most pleasant person to begin with and my girlfriend sensed it. When she left my sister blurted out loud “wow she’s ugly, you can do better!” I wasn’t entirely shocked because she says dumb and rude shit all the time. But it pissed me off, she laughed a little and said she was complimenting me and that I could do better. I got angry and lost it I told her she was a mentally challenged loser and whore and that’s why her husband left her stupid ass to be a single mother, and that kid would be better off with his dad than with her, because at least then he might have a chance at being a normal human being. 

She lost it and started screaming at me, calling me names and throwing shit at. I left soon after and a few days later I got a call from my dad telling me not to come over because my sister is still angry and will call the cops on me and say I hit her if I come by. Was I in the wrong here? 

SOLUTION: EVERYBODY

PROBLEM: My friend added a snap to her story asking for positive messages because she was in a bad head space. Being the joker I am I send 2 messages "-1×-2" and |-3|. I was left on read. I'm bad at gauging situations and if that was a bad response. I'm also not sure if I am reading too much into it. I thought a joke might cheat her up. Was that an asshole move, though?

SOLUTION: NOBODY

PROBLEM: A few months back, a colleague and I started training in a very competitive graduate programme. While working in the same city, each of us would be based at a different centre: one at a nationally recognised institution that arguably is the more prestigious place to work and train, and one that is more peripheral and probably less attractive to employers. Because I scored marginally higher than him on the entrance exams/interviews, I had first dibs and naturally chose the superior place (the commute was also way better for me honestly). Because he already had some research links at this place, he was quite put-out to be sent to the other centre, and at times it was maybe a bit awkward between us, but I took precedence here and I figure that's just how it goes.

Then, we found ourselves standing against the other to be the student leader of the academic course. In a bizarre and kind-of unprofessional arrangement, people had to verbally vote for who they wanted and explain why. I won the vote almost unanimously, and it was a bit of a cringe-a-thon basically. While we never argued or anything, it was kind of obvious that we weren't going to get on too well and generally stayed out of each other's way. He did drunkenly have a bit of a go at me in a taxi not long after, but I was drunk too and earlier that night I'd (accidentally) knocked his drink all over him and things were a bit high-strung with exams and stuff.

So skipping forward a few months. Working at this big centre, I've talked to my workmates about all this, and this enmity between me and him has kind of become a running joke. I haven't made stuff up or anything, but I've sort-of painted him as this bitter and unpleasant guy, which is only half-true really. When he came to my department for a meeting the other day pretty much everyone had lined up behind me and were definitely cold to him- not horrible, but way chillier than when they met me. He is also a really masculine, muscly Russian guy- I am a gay British guy who is arguably much more savvy about office culture and how it works. While I'd never play "identity office politics" or anything, I think most of the staff have judged him before meeting him, and I haven't really made any effort to stop this. 

There is one job at the end of this programme, decided by the staff at my centre. Am I the asshole for cultivating a certain attitude towards this guy in my workplace to ensure I have the best shot at a job, or is this justifiably cutthroat?
