If that guy had just offed Ryuu....
What right does he have to talk about a man using a woman, or how to form a lasting marriage?
The dude actively tried to break apart Joe and Yuzu, and it wasn't because he was concerned for Yuzu...it was because he wanted her.
The dude never considered Madoka's feels.
Ryuu is a serial abuser...it just happens his abuse is mental and not physical.
