[Harry Potter] Did Harry face ANY consequences, for his use of Unforgivable Curses? Where'd he learn to cast them, anyway?

Harry learned the Unforgivable Curses from Barty Crouch Jr who disguised himself as Mad Eye Moody who was teaching the Defense Against the Dark Arts class in year four.

Did Harry suffer any consequences? Nope. The only people he used them against were Death Eaters who weren't exactly in a place to take Harry to court and a Goblin Who isn't even human anyways.
