I watched Everybody Loves Raymond with my mom when I was young and she told me every single character in it is demonstrating some fatal character flaw, and these people are models of how not to be.
Raymond is an insecure people pleasure who bends to everyone's whims and lies pathologically because eh wants people to like him more then he wants to have a spine or principles.
Robert is a cop (and deeply insecure)
Marie is overbearing, manipulative, and doesn't respect anyone's boundaries.
Frank is a caustic asshole who can't let his guard down and just be kind yo the people he loves.
Debra is a pushover who puts up with these other assholes who make her miserable instead of just saying "y'all are pathetic, I'm getting a divorce from your entire family". Yes she complains and tries go be the voice of reason, and that's good, but she never succeeds because it would be impossible for her to fix these people
