Is this Islam’s fault?

I’m trying to sort this one out.  When the law of the land is inhumane, who’s fault is it?  I believe the person that opened the valve on the poison gas at Auschwitz is a culpable as Adolph Hitler for the deaths of innocent people.  If a person igonres the humanity of another, it is that individuals fault, not their religion, or any other excuse they offer.  At least, that’s what I think this morning.
