Raphael's Contract

So, i just beat that silly game for the third time and i always end up signing Raphael's contract to get the hammer (that i will eventually never use) but later destroy that exact same contact at his house and now I'm wondering what happens when i don't destroy the contract. whats the alternative end for that? Will he just get the crown himself and then be like ,,thanks, fuck you, goodbye'' or will I end up as his slave which i doubt because the contract doesn't involve my soul or anything so yeah.
