I don't think that they have an actual devious trait, although I remember that in one of the commercial/preview they had for it. I think that that was from the old version before they edited it for final release.

no, there is no murdering in the Sims
My guess is that you can't make your sim to a vampire on the sims 3.
Yes Vampire Sims can become pregnant in the sims 3. In fact vampirism is genetic in sims 3. eg: Sim+Vampire= Sim/Sim/Vampire/Vampire Sim+Sim=Sim Vampire+Vampire=Vampire
i guess you could do that in the sims1 but you can't make your sim nude in the sims3.
Yes you can the vampire sim can do the same as a normal sim.
