Hi Asarya,
I'd like to answer on your profile (so I won't derail the thread).
Yes, I do believe that man is evil and that violence is in our nature, but to be honest, I have a skewed view on mankind.
It's probably because I cannot filter out negative experiences (reports on war, crime, ...), and for some reason I have always been angry about such things.
My image of mankind is a violent, irrational and selfish one.
I do realize that I should keep these wild generalizations to myself, because one who dwells in negativity, dwells alone in it.
