Loved your post, and can't help but agree. The angry young man with a bitter past has become a very very common trend and like you, I didn't always understand it, however in Rudra's case it makes perfect sense to me.
As you mentioned, Paro had a heartbreaking childhood, but a proper environment filled with love and care made her outlook more positive towards life. Rudra on the other hand...did he have anything to fall back on? We don't know the entirety of his past however from the looks of it, there seems to be nothing but negativity - whether it's his father who feeds him with his idea regarding beautiful women, the attitude from his schoolmates, his teacher...and then joining the army must have made him plow all of that anger into his work, which will turn out to be a sole importance.
I'm loving all the discussion on the forum, it's great to see! But then, after such an impressive episode it is kind of expected😊
