The All Loving God?

Leviticus chapter 20 is just a blood bath. It commands you to kill homosexuals, adulterers, people who fuck animals, and all other sexually taboo people. That's the Law of God given to us by Moses.

I thought in Exodus it says "thou shall not kill", but I guess as long as they fit those guidelines it's perfectly fine. 

And what kind of all loving being would even make a place similar to hell? Where just because you never believed in him you burn forever in a pit of fire? What if a man got shot and his last words were "God Dammit" out of pain? Would he just burn forever even if he was a very devout Christian? What about all these other religions? Even if they are good people, doing good things for nothing in return, are they banished to eternity in Hell? What all loving being would do such things, and make such a place. Especially if he claims to be all forgiving.
