What literature to read if I want to at minimum get an idea of what having a good character entails?

Lately I have come to dislike people who get very emotional and let their emotions override their judgement, physiologically I know what is happening, the amygdala is sending a signal to the rest of the brain that the person is in danger, so the brain pumps out adrenaline and cortisol, HR accelerates, you begin sweating, and your emotions take hold. Unless your frontal lobes are powerful enough to catch this and recognize the reaction for what it is, then you have control over your emotions. This is why people who practice meditation always feel more grounded, because their frontal lobes get more robust.

My problem is not that I´m annoyed that people are overly emotional, it´s like being annoyed at people who are born deaf, or blind. I´m not annoyed at them, I´m annoyed because I see myself in them and fear becoming like it.

So I spend some time going back and forth in my own mind about actions I took, to figure out if what I did was correct or if I had a lapse in judgement. BUT. I have no role models, I don´t know if a good character and morals are set in stone, I suspect they are, but if they are where can I read about them? I´m going on a buying spree, I have some Seneca books and Aurelius, but that is about it. What do you recommend?
