Balance

Humans have one basic mold. They are in perfect balance: they are violent and peaceful. The people we call monsters show the violent side.  Us humans we are in a constant battle: who we want to be and who we are. We want to be good, pure, make the right decision and help everyone. But in reality we are violent peaceful beasts reaching for the idol we ourselves have created. The idol being God: someone who is good and redeems all our human qualities.
Those who fight against our violent side without acknowledging it are by definition stupid, they fight against something they don't understand.

¹stu·pid

 adjective \ˈstü-pəd, ˈstyü-\

: not intelligent : having or showing a lack of ability to learn and understand things

: not sensible or logical

: not able to think normally because you are drunk, tired, etc.

Now don't go thinking I have an emotional preference to the violent side, just don't think or attack me on what I think. I am stating a fact.

We do not crave peace. We crave for the fight for peace.
