First Demonic Dragon by AnathaShesha

In fact at one point the MC got attracted to a taken woman, and naturally as the world's sexiest man alive, she was also attracted to him, however she remained loyal to her loving husband who had treated her well. However don't worry, big daddy author gives the MC whatever he wants. All of a sudden the husband starts getting jealous and aggressive, even planning to kill the MC at some point, and we can all tell how well that went, but before that, just for extra measure, the loving husband decided to slap his wife for the first time and ruin their relationship.

He found out that 1 of his women was tormented by a human in the past so he understandably goes to get revenge. However not sure understandably he decided to destroy the entire city. Also the 'church' was quite evil and were exploiting a poor little girl because of her innate holy physique, basically taking her blood, hair and other stuff to enchant their weapons and armour. But the demons that he later interacted with weren't all bad and were even related to his father. Funny that.
