Or, I think that if there's a God, she/he would have made people with free will so they can do what they like as long as it doesn't hurt anyone. I also think a living/loving god wouldn't have any hate in their heart.

I suppose, what I really believe is this.
An omnipotent being that can't stop the horrible stuff in the world isn't really omnipotent and if she/he isn't omnipotent, does she/he deserve to be worshipped?
If god can stop the horrible stuff but doesn't, again, is she/he really worth the worship?
