I sometimes think/plot ways to kill people?
Firstly I want to say that I am not a violent person by any means, no matter how mad I get. And these thoughts are purely thoughts and never acted on. But sometimes, when people either piss me off, make fun of me, or offend me (or cause me to feel bad or annoyed, even jokely) then I will calmly deal with it while in my head I play out multiple scenarios of me killing them or hurting them, in detail, and how I could get away with it and which way would be the best approach. I know it's crazy, but... is it normal? Don't people naturally have these urges?
I would never ever act on these urges. They are purely thought.
