You are not the One who has been sinned against. You cannot set up the rules for forgiveness.
Are you really saying that if I am wronged by someone I'm not allowed to forgive them?
Jesus want you to forgive them if you feel wronged. You are not qualified to forgive their sin.
If I am the one wronged, I am the only one who can forgive them. And I can do so without the spilling of blood.
Again, this demonstrates your concept of a god is a petty, finite god, and an example of how Divine Command Theory and Vicarious Redemption are the foundation for a moral system.
