I agree that a life lived in obscurity would probably be both appropriate and healthy for MY.
I want to expand on a comment of Neko's: she observed that MY has spoken in positive terms of his experience of being abused by a priest-predator when he was 14.  We know that the nature, extent and effects of abuse differ from person to person; and while the experience of abuse can never be an excuse for abuse, it can be a contributing factor. It's an insidious cycle. One effect, for some victims, is a skewed sense of self and of the world, and a profound, pervasive lack of empathy for other people, including other victims. Healing is surely possible, but it's hard work -- and perhaps it's time for Milo to begin that work, in earnest -- and in obscurity. He's harmed a lot of people; to deal with that, he needs to get real about the harm that "Father Michael" did to him.
