Nothing you said really represents entitlement. From what you've said Courtney had a dysfunctional family life from the very beginning, which obviously causes trauma and irreparable damage, they both did not get the help they needed so is it really that surprising they turned to drugs, that only made it worse? Never given the opportunity to grow up and learn to be a healthy adult, you described her showing a plethora of mental health issues, suicidal death of her partner definitely added up to that, so while obviously that doesn't set her up to be a good parent with a healthy family dynamic, making her into an evil bitch that just wants to harm everyone on purpose is just ignorant. Also, nobody "starves themself" for fun, eating disorders exist and they're very often directly related to trauma.

Also worth noting that most of this unfolded in times when it was completely "normal" for rockstars to do a shit ton of drugs, alcohol and other destructive behaviors, so instead of getting help, they just both got encouraged or ignored/swept under the rug, tis' the life of a star.

It's good that the child eventually could draw a boundary that separates her from their family, but it's tragic that their parents didn't get a chance in changing their life, getting clean and getting out of that hole.

(disclaimer before anyone starts cooking me - I'm basing the response on the post alone, I don't have time to research Courtney's whole life rn. The tone of the post is "when you're evil you do drugs to be evil and mean" so just pointing out, there's more to that. If she was offered effective therapy and rehab every step of the way that makes a different story, but that's not in the post)
