Peoples safety in hatred

If you can take the easy way out in life as not blame yourself of your own mistakes.
If you just easily just say its them that did this to me.

And war is so near to this so you can easily say people are willingly to fight other if they believe that it will help themselves.
As you may know anyone will do anything to survive: steal, hurt and sometimes kill just to survive.

A scenario might help.
You are in an unknown place all you know is that there is only one escape.
You suddenly hear, “cut of one finger of that man and I will spare him, if you dont do it ill kill him then cut a finger from you,,

anyway you do it you inflict pain direct or indirect.
Did you cause it?

Or a much clearer scenario..
you are poor, sick and hungry.
You see food in sight and think the poor can steal if it is the only way to survive.

But the one that did the food need money to feed the family..
who is the evil one?

But to the point. people hate others especially if they think that it will solve there own problems..

just read history with the witch hunters, Hitler, usa (the OIL PROBLEM).. with more..

question...
why is it harder to love then hate if both are so strong emotions?
