Why do we care for people?

Because we are imperfect and weak, that is the reason for becoming fond of someone, so you have a certain security, emotional strength and it can be the cause of unfair actions, preferences, as well as the origin of incorrect ways of making decisions.

In addition, everything emotional has strong doses of irrationality, this does not respond to logical foundations, that's why we are too imperfect.

A truly strong person must be incapable of becoming attached, so they would act with more justice, they would observe alternative solutions to many problems that they do not want to touch for fear of not satisfying public opinion.

Affection implies taking sides for something or someone in certain circumstances, it may seem like a strength, but it is one of the obstacles of the human being, so one of the goals of the human being must be to overcome those signs of weakness that prevent acting in a logical way. . This may seem harsh, but it is what the human being lacks to conquer the universe.
