Interesting topic indeed. I do have an assortment of characters, but I don't know if any of them are the villainous type.
I do have characters that have a jerky and rude personality, and some could consider them as having an evil temper. For example, I have a bobcat character named Benetaur in this family of bobcats I have created. I gave him a personality that is barbaric, crude, and impatient. In his backstory, his family refers to him as the crazy uncle/son/brother nobody wants to be around. Being a bobcat, he lives on his wild instincts to fight for territory, mates, as well as bragging rights. Even if he comes off as rude, ill-tempered, selfish, and unkind to some characters he really isn't evil. Sure he's killed a few warrior cats (as far as story goes), but he had his reasons for doing so. In the wild, any bobcat would kill a domestic cat if said cat invaded their territory, or posed any sort of threat. Even if he does have killer instincts, he still has a soft spot for his loved ones.
Another character I can think of to be somewhat of a villain, depending on how you look at her, is my manticore character, Melina. Manticores are seen as terrifying man-eating beasts. She does eat humans, so some may see that as being evil and gruesome. But to Melina it's only natural. Melina maybe a big, terrifying man-eating beast, but she's old and withering with age.
