She's stupid, but she's also a bit of a psychopath that lusts over the violence in power.

I admit I personally underestimated her, when this all started. She was clearly stupid, but I wasn't sure if she was evil or not. I don't think she's evil in the same way Hillary Clinton is, but she is evil, and I admittedly didn't recognize that at first. I think she's more stupid than she is evil, but it's important to acknowledge that she definitely is still evil.

Also, "psychopath" is a good description. Her brand of evil definitely trends more toward the insane and power-hungry brand, than some of the more "pure" applications of evil. She's selfish and greedy, primarily. That lends itself towards evil, but she's not quite that same level of bloodthirsty as some other evildoers. It's up to the individual to decide which is worse, but there's certainly a distinction.
