Dark romance manhwa

I think a lot of you are familiar with those dark romance manhwa (Bastian, Cry or better if you Beg, Dark chain...) . I appreciate reading them because they offer male leads that have a lot of flaws, questionable mental state,... Of course the only thing that I don't really like is the endings where the female leads end up with the ml. For me those stories are more psychological than "romance". On top of that I like making fun of the stupidity of those male leads. But recently, I've seen an interesting comment stating that those kind of romance are only Korean Propaganda to make them think that abuse is okay. I have to admit that I have never seen things that way. What are your thoughts on this genre ?
