You should also know that at a point when aria didnt have much power she was basically saved because oscar listened to his sister. At that time she couldnt really protect herself if iris did something. Iris said she will harm aria if oscar meets her this oscar listening to iris. Its easy to disobey someone but faving the consequences is not. Specially when the conseqyences involve someone u like.

Well i kinda feel sorry for oscar. Like what's his fault? Last life and in this life too all he did was follow his sister's orders. He was just a puppet. But Asher was kinda petty with Oscar due to his jealousy.
