I’m a Muslim, Islam is perfect but I am not. If people commit horrible tasks, don't be simple minded and automatically blame their religion because their Muslim! Blame them, their religion didn't force or pressure them into doing anything!
"Allah is fair" It's all the same you reap what you sow, Allah means God, there's only one he just has lots of names and demi gods act like demon brat spawn sometimes. Religion cannot separate what faith brings together, or what Destiny conspires.
