Bad parenting

What's your definition of a bad parent?

I have a person in my family that thinks she's a good mom b/c she doesn't drink or do drugs. Imo there's a lot more to good parenting than being clean.

Btw her and her bf have so much drama (fist fights, cussing in front of their kids, hitting them, kids are around a pedophile) I would NEVER allow them to watch my son. She is also the type to insult children to hurt the parents. .. I would call her a horrible mom, I'm honestly surprised that she openly says she's a 'damn-good' mom.

Idk if I'm being overly judgemental or what but I would classify her as a bad mother.
