I don't think many Christians have problems with killing (I've been told many a time that the whole "thall shall not" thing is problematic when it comes to translation, which sure... the word of god is pretty ambiguous I suppose).

So maybe god said not to kill or not to murder. Ok, the killing thing seems pretty simple, but the Catholic supermajority of the Supreme Court has no problems with the state killing someone, but they won't let a mother do it to her baby, so maybe in that case they think it's a murder, which is almost definitely against Christian doctrine, at least that part of the Old Testament.

I figured since it was so confusing, I'd just ask Jesus since he's God's messenger and he's got a facebook page where I can contact him. He's actually big on the first breath thing - they can just recycle the soul into another host body up until then anyway, but every once in awhile they fuck it up and put a male soul into a female body or vice versa and then that's a whole thing and The Republicans have a problem with that too.
