when they asked you companions asked you did you say no and if so who did you go too to get another companion quest ??
I went and did some radiant quests before going back and becoming a werewolf when I felt my character would do so himself.
Vampires are generally evil cause they require to svck the blood of humanoids which will either kill that person or turn them into a Vampire... Basicly, Vampires HAVE to kill and "eat" (So to say) people... So generally, they are evil.
Wrong and here's why.
Angel (Buffy) fed off pigs.
Blade had a serum
Other Vampires in the Blade films had familiars that they fed off but kept them alive
Mick Saint John (Moonlight) fed off bloodpacks he got from his vampire friend working in a morgue
As did most other vamps in Moonlight, even though they did keep human familiars who agreed to feeding the vampires their own blood but not at the cost of their own lives.
Angel, Blade and Mick Saint John are all examples of heroic vampires, though they are not the only ones.
