How terrible can literacy be?

People often say that illiteracy is terrible. However, education is even more terrible. In our life, literacy should actually be interesting. But I'm afraid of those bad people who are literate but have bad intentions. This is what is often said, hooligans are not terrible, but they are afraid that hooligans have culture.

A person's inner nature can be reflected from the external performance, and a literate person can see that he is different from others from his temperament and behavior. When he has enough knowledge, it will be reflected in his own speech, showing independent thinking and keen vision.

I can often see some unexpected depths and have my own unique views on the world. Quality and education will be reflected in the details of his behavior, such as dining etiquette, such as opening the door for others or holding the elevator door, which can reflect the good education and high emotional intelligence of this person.
