Personally, I find the thought disturbing, that others want to kill, whether acted on or not. I just think that thinking that way is abnormal. But who knows (or cares really)? Maybe it's me. But , I'd prefer not feeling there are normal people who think about randomly killing others out there.
Actually it is pretty normal. I know plenty of people who have thoguhts like this, including me.
Tbh, i feel as if i one day will act upon these thoughts/feelings but most of the time they are unrealistic. Like killing my friends GF with a toothpick, just stabbing thousands of times.
