The analogy is the "wife beater". He's bigger and stronger than his wife, and it makes him feel better to take out all his frustrations on someone who won't or can't fight back.

Then if she complains, he says "you shouldn't have made me angry", or "I only got angry because you forgot to pick up the mail" (she did pick up the mail, but he makes her doubt herself). Then he offers to make amends by saying "look, it will be ok, I just need you to do this and that". He completely manipulates her until she breaks - until her owns her completely. Battered wife syndrome.

It continues like this until she recognizes what he's been doing, then takes back her life. And the bully continues on with someone else, or until he gets his comeuppance.
