Trust me when I say someone like Inseop is not capable of healthy love. He was born this way, completely lacks affective empathy and only has very intact cognitive empathy. He is the definition of a Primary psychopath 

I say this as someone with some traits that are similar to Inseop's (lack of empathy, no remorse - guilt, etc), but I have ASD and it gives me a moral compass/limit.

And honestly, if someone came up to me and asked me if I loved them; it's a direct

No, I cannot love people and I'll literally break their heart without feeling anything. It's like an exchange and the person is not necessarily a person; just something there interacting. If relationship, it's utilitarian type. For some people, affective empathy and emotions are just literally absent. You can fake due to understanding, but it's absent meaning they will never feel love like the general population/most people. If emotions are not there, you can't love anyone or feel anything for them. You can understand what they feel and etc

People like Inseop cannot love, they can understand what "love" is, but it is not love.
Does it make sense "how he came to the conclusion"?

It's just in his mind. He wants to own her as an object and not a human being. 

Im also here for the psychological thriller/psychology of each character.
But I don't see what's wrong with the moral part tbh. Psychological takes are interesting and helpful to understand patterns? Just Imo.
