He might be weak and a coward but he is not a bad person and doesn't deserve to be used, tossed around and played with his feelings to have in the end, marry someone he doesn't love to protect the one he loves.
I personally don't like him as a character, yeah, just cuz I simply don't but that doesn't really mean he doesn't deserve better.
They wouldn't listen to him first because she is supposedly Crown Princes future wife, so she hold higher status than him. Second, because Aria is a daughter of a prostitute, no one would agree with him to not marry Mielle or whatever was her name but Aria instead *just cuz they are dumb fawks* sigh, and third, his sister is way smarter than him *even tho i dont like her* so there's really no way that if he went against her anything would change. And Aria might've helped him, but not cuz he likes him or anything, but cuz it would lead her on the way to the revange. But tbh I can't wait for Aria x Prince woop woop his sister will be so furious MWUAHAHAHAHA and Mielle ! Mwuahahaha
Oscar deserved better gosh he's innocent to all their schemes of isis and the trash but like man I pity him he does not deserved what will happen haisss
