Is it normal that i have intrusive thoughts about killing arseholes?

I have recently been diagnosed with complex ptsd, which I have been suffering from for my whole adult life. I was physically and psychologically abused for 13 years of my childhood, and amongst the many things which trouble me (sleeplessness, hyper vigilance, dissociation, anxiety, depression), my detailed, gory intrusive thoughts about how I’d like to end some people are most troubling of all. I’d never hurt my loved ones, but the people who have tormented me, I sometimes think are treading on thin ice. Lately I was assaulted by an asshole neighbour for no reason at all, and since then I can’t shake the desire to mutilate him then kill him, slowly. Everything from petrol bombing him in his car, to removing one of his eyes with a knife and making him eat it has occurred to me, and worse. I’m frightened of what I might be capable of, and I feel closer than ever to snapping. Luckily I’m getting help soon, probably not a moment too soon either.
I feel like the world is going crazy, and that this violence I feel is rubbing off onto me from society at large. Anyone else feel this?
