The "Hanoi executioner" has traditionally meant "one who kills" and usually refers to the person who carries out the death penalty, utilizing various kinds of weapons or tools used to execute a criminal sentence. This act is usually done publicly to proclaim the majesty and fairness of the law.
However, though, in history, the executioner was very important, and the function acts were demanding in courage and determination, having in mind that the act itself had great social influence and put a great psychological pressure on them. With the progress of modern society, many countries have wiped the death penalty off their laws, so with it, the figure of the executioner. But wherever the death penalty is kept intact, there exists the coveted figure of the executioner.
