I mean, wanting to have a relationship with some guy that has a history of killing women seems like a bad idea for a woman.
Admittedly, if I picture an attractive murderess I suppose I can see how it might be appealing on some level, but he's in prison so it's not like they can sick him on their enemies or anything and I'd still prefer my attractive murderess to be inclined towards targets other than my personal demographic. Plus, they don't know the guy except from court transcripts and so on, so it's not like he won them over with his personality (and yes, personality is a heavy factor in attractiveness to me).
So... Yeah. Crazy. It might be different if they'd gotten to know him prior to his arrest and just loved him so much it didn't matter he'd killed a couple people (though that's still a little crazy, it's not "clearly evolution is failing" insane).
