The phrase "assumes facts not in evidence" seems relevant here. Nowhere did I say I don't get annoyed by murderous or villainous characters. On the contrary, as I said, I read mysteries precisely because I enjoy seeing good triumph. Dislike of the villainous characters is, for me a given, not something I should need to explicitly state. I have no problem with the existence of negative characters per se.

On the other hand, when characters the author intends the reader to like consistently display characteristics I detest, that is a different thing altogether.
