My reason for that has to do with the murder of James the brother of John by Herod Agrippa I. This story is in Acts 12. In that story, Peter is also captured, imprisoned, and set to be wrongly executed by this fanatical king. The church prayed for his release and Peter was miraculously released.
On his release Peter did not rail against the king, nor did the Christians agitate for the death of King Herod Agrippa.
Shortly thereafter, though, God Himself took Herod's life due to Herod's own narcissism.
It is a clear biblical example of a true grievous and a true act of retribution by God, and not by God's people.
Your position is ever so unbiblical, and it is demonstrably so. As our friend wagglebee says, there are 3 moral justifications for killing: a just war, true self defense, and legal/moral capital punishment.
God will not bless the murderer of this murderer, because the shooter decided to play God rather than wait on God. Ultimately, "the wicked shall be cast into hell..."

Amen, xzins. I have read the entire thread to this point in time and came back to your post as the one I agree with most. Tiller was an evil man, but imho, you are quite right in your perspective of this event.
I think it may be better to pray that Tiller had true sorrow to the Lord before he died and that God would have mercy on him. Also that his killer will also have true remorse and be shown mercy as well when he dies.
The only unforgiveable sins (by their very nature) are presumption...assuming that no matter what sins you commit, God will automatically forgive you. And the opposite of presumption, despair...assuming that it is impossible to be forgiven, so you do not ask God’s forgiveness because you do not think it is within His power.
