I feel bad for the son, I can see why his personality is the way it is, poor son

Exactly . There's no adult around him who's really interested in raising him and teaching him life lessons. Why even birth children if you're gonna discard them life trash? And his personality is bad but he could learn if someone would be caring enough to spare some time and teach him.
But ig there's no lack of shitty parents in this world. The only problem is that one of that 'parent' happens to be the ML here, and apparently, we're supposed to like such a person because his appearance is good and he's presumably a 'passionate(forceful)' love.

Woah, nobody even cares if he's a horrible father
