I hope I always want what God wants, and He doesn’t want anyone tortured or damned.
Repentance comes from an acknowledgement of the truth, and the naked honesty to say “My God, I am a murderer. I deserve a severe judgment. You are right when you convict: deal with me according to Your will.”
What the killers need is broken hearts, not broken heads.
God can go ahead and forgive them. I will torture them to death.
