Why does GOD do this?

Asking why God killed your friend is like subscribing to a stereotype.

Not if he believes it.

It's stupid, illogical, and unprovable. Using that sort of thinking is akin to saying everyone from the Middle East is a towelhead terrorist. Are you that provincial?

Again, that statement doesn't prove anything, except that you don't believe God, and you think that anyone believes God is simply "Going to fit in with society". I am sure that he doesn't see God like that.
