Adrianna is a bad person

I'm not saying it's not awful to watch Christopher abuse her, and not absolutely brutal and depressing to watch her get murdered... but

Early on she sees Brendan shot in the head in the bathtub. This isn't a deal breaker or a wake up call for her. She's okay with this life. She gets more animated about free shoes than murder. When Christopher is mock executed and in a neck brace, she's not all that concerned. She's more interested if it's true he made #2 in his pants.

She also encourages Chrissy to sell meth to a high schooler. She covers up a murder at the club. She is happy to take over a club from some poor chump the mob has ruined. She's knows there's murder and death in the life she has chosen and she is okay with that.

More than being a bad person, Adrianna is just tragically dumb, but there is still a total lack of any morals or integrity about anything.
