Right, thank you all for the replies and elaboration! Now to go try it, though I realise that I actually have few negative ancillaries - just one Evil Mother-in-Law on one of my more useless family members, who just happens to be Flaccid, a Hypochondriac, Venal, and some other trait that's something along the lines of being adverse to education, along with a host of others I can't recall at the moment. It's no wonder, I'd have become Evil too.
