As they say in AA, he will deal with "life on life's terms" or he won't.
Life on life's terms means that there will be emotional pain, failure, anxiety, humiliation, shame, guilt, heartbreak, broken plans/relationships, pets dying, children sad/afraid/bullied, health scares, health problems, and death.
You are not God, dear, and you will have to just step back and let him and God figure out how he intends to be the one exception on the planet to being human and avoiding having to deal with it.
He is already dominating you. His words were a threat. Stick with SR.
