I'm a spiritual person. I believe I'm not supposed to hate anything that God made. I don't think that God would approve of me hating his kids. I sure don't want anyone to hate mine.
So how do I reconcile my attempt to not hate anyone with my willingness to kill enemies of the state? If I was a soldier, sailor, airman or marine, I don't think I would have to hate people to kill them.
I'm sure that God doesn't want me to kill his kids, but some of them are out of control and pose a threat to the rest of us. At some point, you have to let your kids make their own mistakes.
