Evil is like natural disaster. Ideally, it's not appropriate to blame evil only to the person who execute it.
External factors played the role as well, and crimes in a calm and peaceful neighborhood should be treated different from those that are committed in a war like environment.
But again the question is, who started the war? Who forsee the probabilities of war and peace, and chose war?
Despite the issues, we need to improve tolerance within the society. Bad things that is not a crime should not lead to crimes or jails. This is my opinion.
The scarcity of the world is not of time nor energy, but of working solutions.
When you live in environments minimum of working solutions, would you give in? or would you fight?
Would you fight to create working solutions?
Make the world safer, better, richer... mutualism will win, with or without us.
