After much research I have determined that the original Hebrew text of the Bible says "Thou shalt not murder", as opposed to "Thou shalt not kill"
The difference may seem semantical, but there is wrongfull murder, with intent and malice, murder in the commission of warfare, accidental murder, and the intentional, and justified murder to protect another life.
We can all agree that Hill murdered another human, the only question is whether or not that murder was justified. To answer this question truthfully, puts most all of us in an uncomfortable position because there really is no middle ground.
If you believe that life begins at conception and I don't see how anyone could objectively say otherwise, then Hill's actions, were morally justified. Notice I didn't say legally justified. The fact that the state sanctions the murder of innocents under the color of law has little to do with this. Only if you believe that the state is infallible, do you have a case to vilify and execute Hill for stopping the wholesale slaughter of innocent children.
Another poster has rightfully chastized the rest of us who believe that this is allowed to occur due to our inaction and he rightfully points out that we will be held accountable before God for it. To take such action, in the face of his own execution for it takes a kind of courage that most of us will never have. And more's the pity.
