You can't really dislike the dwarfs, especially considering they encompass every personality trait. Despite Grumpy's initial reluctance, they give Snow White a place to stay in the forest to avoid the evil Queen.
Why they're better than Snow White: First off, someone should have told Snow White to never take food from strangers. None of the dwarfs would ever have fallen for that. AND in the end they were the ones to kill the Queen.
Fun Fact: Other named considered for the dwarfs included Busy, Crabby, Daffy, Dumpy, Flabby, Helpful, Lazy, Scrappy, Sniffy, Snoopy, Stubby, Thrifty, and Wheezy.
