Eh, I learned a long time ago that Joss Whedon sees characters and stories very differently than I do. This is the same guy who thought it was no biggie for Xander to summon a demon that killed several people, and play the revelation for laughs, and who (if Jane Espenson is to be believed) honestly thought it wouldn't be that big a deal for Spike to try to rape Buffy. Or for Angel to lock a bunch of people in a room and let vampires eat them, or... As Buffy will probably end up saving the world by the end of the series, I'm quite willing to believe that Joss doesn't think it's any big deal that she doesn't care that Angel's killed hundreds of Slayers and possibly thousands of innocent people who got squished by hurricanes and volcanoes in order to give her sparkly sex.
