Too Evil

I was thinking about character development, and I wondered if there was such a thing as, too evil.

The answer for me is, yes.

It's not that evilness, or any other character trait has limits. It's that a character must be developed so that their actions make sense. I do not like when I read a story, (or watch a movie), and I'm taken on a dark ride that I do not feel is justified, 

If I get a sense that something was written because the writer thought it sounded good over what the character might actually do-it doesn't work for me. 

In Dracula, by Bram Stoker, for example, the reader can believe in the extent of the depravity.
