Okay, what. Raymond knows full well his anger towards Agnes is unjustified: she neither caused his father to be obsessed with another woman nor caused his mother’s death. Yeah, Agnes was a brat using her authority for stupid things but she was also nine yo(?) with nobody to teaching her any better.
But then Raymond just admits he continuously punished her, causing her to fall ill and get hurt and such repeatedly over the years. Sir, you are also immature.
