Nothing at all. Perfectly fine result.
I truly don't know where this "impossible ideal" thing is coming from. In effect, EVERY time you play a role-playing game you should be doing this. It's part of role-playing. I mean, I assume the ideals, bonds, and flaws of your character are not shared by you as a player, right?
Deciding to do something which isn't optimal is a pretty standard aspect of role-playing. Heck,
it's even in Matt Colliville's video on metagaming. Yes, doing what your character would do rather than what you think is the most optimal thing for the situation IS role-playing. It's a pretty basic aspect of role-playing. I just don't know how others think that's weird or any of the adjectives you and a couple of other guys are applying to it, like it's a foreign concept to a role-playing game.
