If you really want to delete categories, you need to get a bot. Humans can't delete categories, except with a lot of menial labour, for precisely the reasons that Elecbullet mentioned. You have to go to each and every page where the category exists, delete it, then return to the category page and delte that. With a bot that is also a sysop, though, category maintenance is a snap. Not only can you delete whole categories within a few minutes, you can also usefully rename categories.
