Abstract
This article will be about the gravest of crimes, a crime that is forever irreversible—murder. Alas, humankind has borne the mark of Cain from its very beginning. Once upon a time, on the earth, there were only two peasants and their parents, and brother killed brother. This is how it all began. Of course, we shall not venture to journey back through the mist of centuries, but let us look at how things stand right now.
