Many people put themselves in boxes. For example, evangelicals may think of themselves as Christians, but may only care about whites who think like they do. The head of the Christian Century, an important publication, had created the word evangelical to describe certain Christians. After this group went overwhelmingly for Trump and his racist message, this distinguished theologian said they no longer deserve that designation.
In addition to those who put them themselves in boxes and only care about others in their box, there are the truly dangerous people.
These are people like Donald Trump and El Chapo, and other drug kingpins, who are incapable of compassion for anyone that is not in their family. Because they can't empathize with others they are more dangerous than those in boxes. Under no conditions would they ever understand what others are feeling. Therefore they are incapable of changing, or growing. Putin is like this, so of course he'd want an American president who was as soulless as he was.
