Disney needs more "good" Female villains:

I was really scared of Maleficent, of Ursula and of The Evil Queen. I really like the most the male villains, b/c I find them bad, but not so cynical and petty, their plan is not so complicated and malefic as the female villains' plans. That's my opinion.

I agree. Maleficent creeps me out, but she's one of the "good" villains, if you mean creepy/good at villainy. If you mean good as in nice, Shock from Nightmare Before Christmas is a good example. She worked for Oogie out of fear, according to the song. Mother Gothel is also a good example, since she was nice (or at least pretending to be nice). Gothel's songs are good too.

i wish they have more female villains but ursula scare me when i have nightmare dream

I personally loved Ursula, The Evil Queen, and Maleficent. Mother Gothel is also pretty great.
