Well, Ratcliffe from Pocahontas is a weak villain anyway to hammer the point home about how Anvilicious and Oscar Baity that film was.
But then again, you look at the Disney villains...
Scar, while wanting power, also fell victim to the royal system that puts his nephew in front of him... Ursula was banished by Triton for some reason (discounting the canonical iffiness of them being brother and sister)... my personal favorite, though, goes to Yzma. Now, while she is evil and has evil intentions for taking over the kingdom (and in an episode of the TV show she does and it's awful), she works for a hero that's a complete self interested jerkwad, so you would actually almost feel sorry for her if she wasn't just as self centered and nasty. But then again, that movie's all about viciously subverting Disney movie cliches, and plays around with designated heroes and villains.
There's also Beauty and the Beast where Gaston, sack of crap that he is, isn't so much the villain as completely convinced that he's the hero of his own life. Wrong genre savy. His motivations are essentially wanting a woman that doesn't want him back for the reason that she doesn't want him while ignoring the blonde triplets that constantly throw themselves at him. It's ambition, sure, but he's deluded, not technically evil. If anything, he's as evil as Daffy Duck.
