Delta was only trying to help, not trying to upset him. It sort of went hand in hand during this situation though, sadly.

I know. Jack, the only way to let yourself go is to try and forgive him. If you don't, the hurt of what he did will just repeat itself. It doesn't matter if he was "worthy" of forgiveness or not.

I know this from experience.

He did, didn't he? Delta was no stranger to rage and cruelty. He was accused by Stanley, sold out by Sinclair, stuffed into a suit by Gil, and forced to deal with Sofia to get Eleanor back.

He forgave, not for them, but for himself.
