Exactly. You either believe in the sanctity of life or you don't.
There are precisely three circumstances under which it is morally right to take the life of another:
1. In a just war.
2. To defend yourself or another from an immediate threat to life.
3. A legitimate execution of someone who has been given due process of law.
Your 3 instances of moral killing are exactly right, Wagglebee.
And on #2, it must be, as you say, an immediate threat. For it to be an “immediate” threat, one must be proximately related and proximately present.
I do not want to give the impression, however, that this abortion doctor was a more moral person than his own murderer. He is no hero.
Tell me wagglebee, if you were chosen for the jury on the Tiller Murder case, would you convict him?
I know I would vote "Not Guilty".
Ultimately the final arbiter of right and wrong and of guilt or innocence lies with the people and their ability to vote their consciences while sitting on a jury.
Yes this guy broke the law and should be called to account. But those who ultimately sit in judgment of him are bound only by their consciences. I would hope he receives swift justice.
He should be promptly arrested, given a fair trial by a jury of his peers and ultimately acquitted.
