Another example of bad character traits are when someone descends from a polygamist, abuser, etc.
They might not marry multiple wives, but they'll have a line of girlfriends of whom they play house with. They can't commit to anyone and build a real life or have a fulfilling, healthy, intimate relationship. They string along one girlfriend as their main supply (fulfills the role of first wife), and a second for show, and maybe a third just for sexual pleasure. A second example is someone who comes from an abusive ancestor. They won't physically abuse their partner, but they'll mentally and emotionally abuse their mate.
They know that polygamy and physical abuse is outlawed in USA and carries legal disciplinary consequences. Therefore, they exercise these traits in a way that avoids jail time.
But nonetheless, such people are very toxic and leave a trail of broken people.
