Here is hoping he actually finds out sooner than the rest of the Super Hero Community, by being one of Steve's first victims.
Of course he survives this somehow, hey he took down Steve once on his own and this time he has a team, and goes on trying to convince the other Heroes that Cap is evil.
Being a Pariah to them and Cap still being the symbol of everything that is good in their eyes would make that quite the struggle and I'd love that.
