Are some people born to want to kill?

Because some people get so mad or upset from someone who did something to them that made them very mad. When I get mad I want to commit suicide. This can be normal but since I'm an 11 year old girl it's not very normal. If your getting bullied at school then that's a normal thing. But people get so angry they are willing to kill. Now if this is you don't kill. Think before you do. If it gets to that stop and think. Take your anger out on a pillow. Draw a picture if the person you want to kill and tape it to the pillow. I stab it with a tack and I punch kick and do whatever I want to do to their face. I hope this helps with your question. LIVE. LAUGH. LOVE. DONT KILL
