Was the male lead of this novel childish and black-bellied?

I recommend the novel "The Rebirth Hermit's Counterattack". Although the male protagonist used to stand at the peak of the era, he became an ordinary teenager after rebirth. He lived a life of caring for his wife and raising his children. Occasionally, he would do some evil things that harmed others and did not benefit himself. It could be said that he was childish and evil. I hope you like my recommendation. Muah ~
