Love to Paris – not Hate!

I am deeply sad about the hostile and inhuman attacks on the people of Paris. My condolences go out to the families and friends of the victims.
My main question now is not, how to retaliate appropriately, but: how can human beings be led so astray to commit such atrocities?
LET’S ALL STAND TOGETHER AND BE AS ONE – 
AGAINST THE HATE OF SOME!
