Deal Breakers for Fictional Characters

A good author – or even a mediocre one, if I am invested in the story and/or characters – can get me to forgive a character a great many things. But there are also things that are deal breakers for me; things that will render a fictional character irredeemably unlikable in my eyes.

( Some of my deal breakers... )

So, d'you have any deal breakers, too? What are they? I want to know! :-)
