I've seen her "live" on tv (vs. in a photo, alone). If she wasn't wasted during live court proceedings, then yeah, she looks evil to me. Her eyes, her expressions, her lack of expression....she sure doesn't look like a girl scout selling cookies. And knowing that she "allegedly" shot him up with heroin, and then casually sipped her wine while his life slipped away, and then closed the blinds so no one would see him....that to me, those actions, are evil, and what she is in her heart, shows in her face, imo. If that's what heroin does to you, then I guess it's evil, as well. If that offends you, I'm sorry for that...but not sorry for how I feel.
She was probably high herself at the time. You can't expect someone like that to react the way you might, so it is not wise to extrapolate from how you imagine you might act and expect others to do the same.
