Honestly, he is way nicer than me. I don't put up with it anymore. It is like politics or religion, just don't talk about it.
But the point is, life is complicated and there are no easy answers. We all deal with problems the best we can.
The Author's representation of the professor is accurate to life. They aren't deliberately cruel or trying to hurt you. They just love and care for a person who was awful to you. Hurting them, doesn't make you feel better.
I'm interested in seeing how our character will ultimately deal with the pain he has been living with all this time. There will definitely be more difficulties before we get there.

I know everyone is going after the Professor and I kinda hate him too, but not for the same reasons.
His reactions are actually quite common. When you love and care for someone, you can't believe that they would really be as bad as someone says they are.
I was in a very abusive situation. I told friends and family, but they only saw the charming person outside, not the screaming aggressive person reserved for inside the home. Everyone couldn't believe it was as bad as I said.
Not until that person lost it in front of others. Then they apologized and wanted to help.
I hate the professor because he represents all the people who wouldn't listen.
I saved myself and have to accept the fact that many people will never understand.
