<human>: Could you distill the essence of the text into 1-3 sentences?

He's a year younger than me. He sexual assaulted me, verbally abused me and my friends, and is a pathological liar. He's racist, sexist, homophobic, and constantly rips on heavier girls. His go-to argument ender is "Kill yourself," and he absolutely means it. And yet somehow, people like him and somehow he has friends. 

I've been waiting for the karma train to come and kick his ass, but it hasn't. He's had a few jobs, is apparently one of the top salespeople where he works now, and got accepted to a few good schools. His life is only getting better and it kills me..the only thing keeping me from getting to the point where I am now is knowing my life would always be better than his. 

I haven't talked to him in 2 years, and yet I still hate him...so much that I honestly wish his death. Almost daily I think about ways to give him what's coming to him...anything from some stupid prank, to completely ruining his reputation.

I guess the only point I can see from this post is an outreach for help. Has anyone else been in a situation where they were consumed by absolute unending hatred, and managed to overcome it? I want him out of my head and I don't understand why he's still here.
<bot>: asshole kid, karma wasn't a bitch, distracted from important things by resent and loathing for him, need help coping/forgetting
