Especially after watching the last episode, it seems to me that vampires largely fit their evil stereotype. I'm not talking about the books 'cause I haven't read them, but the writers for True Blood have certainly portrayed them that way.
Most of the vampires we have seen to date are predatory, ruthless, and consider human beings to be a lower type of lifeform. The ones shown briefly on TV even seem to have their own agenda, and their radical human counter-parts have a habit of dying in nasty accidents. Even recognized vampire "law" takes sadistic pleasure in torturing "offenders" and preying on innocent humans.
The possible exceptions to this rule are Bill and the gay vampire. Gay vampire was new to the ways and habits of vampires, so he cannot be a positive example. "good" Bill obviously has his own sordid past (to judge by his associates) but through force of circumstance is not above turning a human or murdering out of revenge (Sookie's uncle).
Bill and those *trying* to be truly mainstream are obviously a minority, and a weak one at that. Makes you wonder what conspiracy is embedded in the plan to go public.
So do you think they are innately evil, or just turn that way after centuries of living with callous humans who fear and persecuted them?
