Yeah, Angelus long term is kinda scary and creepy. And don't worry, "Cost Benefit Analyzing" really got out any urge to write an Angelus/Xander fic, and that was not pretty. Heck, that story is so short because I had to skip around from point to point to avoid writing torture. Here, Angelus has a reason for wanting Xander alive because he knows the soul will take back over. Without that threat/fear, Angelus would turn into the raping bastard of Cost Benefit.
