What's the difference between a bad man and a bad woman? And why is the line so hard to tell?

My parents are the kind of people I don't know if I would call bad or just wrong. My father is an asshole, a selfish, inconsiderate, unempathetic asshole who can't understand the harm his actions can cause others. He's not even that bad of a man. He doesn't drink or smoke or gamble or cheat or beat his wife or daughters. He just has no regard for anyone else's feelings, he's so focused on himself. I know I will never like him, I know I will never be able to like him. <br><br>My mom, on the other hand, is a woman I would call a bad woman, a woman I would never like. She's a selfish, inconsiderate, unempathetic person who can't understand the harm her actions can cause others. But I know she's not just wrong. I know she's a bad woman. I know she's a bad woman, and I know it's in her nature, it's in her blood. I know she's a bad woman, and that she was born that way. I know it in my bones, I know she was born that way. <br><br>So, what's the difference between a bad man and a bad woman?
