Kill people who believe in Allah and are Muslims and innocent, non-muslim people aswell, in the sake of Allah? I doubt, nope.

There is no 'killing in sake of God" except if it is happening while a Jihad-scenario (not going into this, another topic) or death-penalities (because you killed INNOCENT people). Seems pretty fair to me, you take life of someone innocent - your life will be taken, must admit that even though I try to not support death penalities.
