One of the reasons I keep reading these books apart from how they hit the sweet spot of psychopathic serial killers monologuing and faking human emotion while you feel like an alien, is its incredibly endearing monologue.
"fuck, she trusts you and not me?"
"she can tell that my heart is pure"
"pure what?"
Also it probably wouldn't be. But it'd be somewhat fun. I even made a name for it, even if I'll never write it. "Sylar the kissing maniac"
