Hacking is wrong, this we know;
People make a big deal about not wanting hacked mons in their games, especially events or legendaries. If it can get past the in-game hack check, is it good enough for you? And what about the children of hacked mons? You'd never know that the ditto and whatever parent were both fresh out of PokeGen because now you've got their legitimately made child; with carefully cultivated egg moves and ivs etc.
