While I loved your list of things it would take to get you back, the whole premise appals me. I can honestly say that there is NOTHING that he could do that would get me back into his vicinity. 

I am probably not a very forgiving person, but I simply could not be one of those concentration camp victims who meets their abusive guard decades later and forgives them. No. Nope. No way.

That man took decades of my life and most of my inheritance and destroyed my self-esteem and my will to succeed in life. I despise him and everyone around him who enables him.

Nothing he could ever do could make me forget or forgive him.

That being said, I would dance for joy if he ever did fulfil all the conditions you listed. It would make my heart happy to see him so humbled. But I wouldn't want to be anywhere near him, and I still wouldn't forgive him. He could never 'get me back'. 

I believe he belongs in prison for fraud and child abuse. I simply don't believe he can be redeemed. Lock him up and throw away the key. Let him rot and die in prison.

Too much?
