Last time I saw Disney one he was evil, maybe crazy.

Slight chance evil part I am remembering the one from the Kevin Sorbo/Lucy Lawless tv shows.

EDIT:
Now that I had time to look into it. Hades was definately a villain. In the animated tv series, he was constantly trying to take over Mount Olympus.

The Sorbo/Lawless Hades was a respectable guy.
