Yeah, it's just as bad. Dwarves, elves, etc. are all just as intelligent, just as empathetic as humans; killing them in anything other than the most dire straits of self-defense would be just as wrong as killing a person.
For the vampires and werewolves? What Doclector said: "If it's hostile, you kill it." If the vampire lives by draining people and enslaving villages, feel free to put a stake in it's heart. If the werewolf makes sure he's near humans during the full moon, silver bullet to the brain. If the vampire tries to get enough blood to survive from blood banks, or the werewolf lives in the far north to avoid hurting people, try and help them, or at least don't kill them out of hand; they are still thinking, caring beings.
