Men Enjoy Seeing Bad People Suffer

I was reading an article from the science writer Malcolm Ritter that made me remember conversations with my stepdad, mother, and friends. The article brought up that men might not feel empathy toward people who are bad or cheaters, while women are likely to feel empathy toward them. It made me think of my stepdad because it was describing him on many of the negative reactions described in the article. Just for an example, my stepdad says that if anyone ever did anything bad to him or his family he would seek revenge to make up for it and enjoy it. He also does not feel sorry for any violence toward cheaters or criminals. I have known a few other men who think and feel the same exact way. My mom disagrees she says that people do not deserve to be hurt even if they were bad, she says it's up to the law to take care of it. I have asked many of my friends and they feel that way. This raises the question if there is in fact any differences between males and females empathy toward cheaters or people who did something considered inherently inappropriate by others. Now what about emotional males or vengeful women? These insights still need lots of supporting research studies.
