This is what occupation does to you. War is OK, but occupation is NASTY NASTY stuff. It doesn't happen because of lust but because of rage. Imagin u were a soldier from country X occupying country Y. You have your best friend killed in a skirmish and suddenly u have locals cheering over it. This puts you in a state of topor (frenzy) where you lose all track of rationality and just let your primal instincts loose. It can happen to any one of us, and may God never give us a fate as being occupation troops.
How would u feel if u r family member (GOD FORBID) lost his / her life (JUST FOR EXAMPLE I DO NOT WANT THIS TO HAPPEN 2 U!!!!!) and then I was beating drums and celebrating it? Would you be nice to me when u got the chance to get me when I'm down?
