No prayers for murderers. Ever.
Have ever hated someone in your heart? Ever? Jesus said such a thought is equivalent to murder. Tough standard huh?
All have sinned/are sinful ( violated Gods perfect standard) and are guilty. God doesn’t parse sins. That is why all need a Savior. We are all guilty before God, so and unless we individually change our mind ( repent) and ask Jesus to be our substitute, we are given the death penalty in God’s economy. Sort of like this situation. While he may have found forgiveness in Gods plan, he still has to face man’s “justice” for crimes against mankind.
At least this man shows repentance for his crimes while on this earth.
