Psychological studies have been done on this topic. Player killing or for this game "spawn killing". Pretty much all the studies I have read indicate that those who spawn kill are narcissists. They are more likely to lie, steal and participate in other anti social activities in the real world. The person who spawn kills enjoys denying others the oppertunity to play the game. The act of killing weaker or defencless players gives them a sence of power and control.
After reading these these studies, it is interesting to me to know what kind of person you are if you spawn kill.
