When someone kills another person, we may say that he has the deepest experience of knowing her like a human being. We cannot know a human being better than by reaching to the point where its life ends. The love is also knowledge of an individual until to the point where he or she cannot be an individual anymore, but only a partner.
It is not a kind of knowledge similar to an act of learning theoretical matters, but a plain exposure of the human being impersonated by the victim.
It is so plain, so that the killer might see himself in that living picture of human limits, weakness, fears, and humiliation portrayed by the victim.
In spite of the killer’s desire to kill for getting power over his victim, he is under her power of revealing humanity in its lowest forms. When he continues to be bad, he in fact develops all those low forms of humanity in his person by losing his place among other people.
The remorse which could make him a better person is a form of estranging from his victim. Therefore, the remorse ceases to be about the victim, but rather about the aggressor and about his refugee in that field of shallow and egoistical emotions which dominates the human relations. Those emotions do not contain the knowledge of other persons until to their final point of their life. They are equally far from love and hate. The remorse might bring forgiveness, but not in the name of the victim which was abandoned by the remorseful killer.
