More than the fact that he came to hate omega most and became anti-social from friends leaving him due to his gender error, it's moreso how his alpha family treated him when he was misdiagnosis as omega. Considering how his own brother and every alpha think omega is just a tool for release. I think what he came to hate is the attitude of all alpha regarding that type of thinking, and the beta and omega for weakly believing they're inferior beings.
This is why even though I personally think he already caught on that the uke might be an omega that he still tell him to sleep in his room because he fears his brother alpha-periority. Considering how innocently dense the uke is unlike any other omega servant that came before him.
