Review Detail of EternalCodex in Villain: Manipulating the Heroines into hating the Protagonist

The story is typical but better than most 'villain' novel. Still there are some cons - MC is a kind of sadist. He mostly uses rough ways to indulge in primal desires. I personally don't like it. Though he seems to care about two or three heroines but it still appears that he is just using them as a tool. What's the meaning of this if you don't even sincerely care about an individual? I'm not saying that he should become lovey dovey or like a righteous and kind protagonist but still make it look he cares about someone. It'll make story somewhat interesting. Though it's my personal opinion. I am not against the fact the MC forces himself upon some heroines or/and women but some women still deserve to be treated with gentleness. And just control his lecherous and lustful nature. Don't make him surprised everytime he looks at new heroine and at other things too.
