What do you like about the lifestyle of a medieval knight, and what causes condemnation?

What we like about the life of a knight is that they are presented in literature as the ideal of virtue and nobility. Because the knight’s upbringing was rather harsh, but versatile – the basics of theology, versification, handling weapons, all this made the knight a special person of his time, and his cult of a beautiful lady cannot but arouse admiration in a modern person.
The attitude towards the peasants evokes condemnation. Because the knights did not consider peasants to be people, murder was in the order of things, and the right of the first night was not very fair and true.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
