An act of killing someone, it’s basically a crime where a pupil attacks another pupil with a weapon , and the attacked pupil dies, If you murder someone, you will be arrested with a really long prison sentence, so it’s best not to do it, if you murder a majority of pupils, and are caught by the American cops, you could be sentenced to death.

Person1: Hey, I’m going to murder a random ex-comedian via shotgun,
Person2: Dude, you are seriously fucked up, you will go to prison for this, dumbass
Person1: Fuck off i’m doing hitman shit I’m doing this for $50,000
Person2: You are a mental motherfucker I’m not being friends with you anymore
