6. Crucifixion
We are continuing our list of most painful cruel horrific deaths and execution methods in history with not only a painful and cruel way of execution but also humiliating. It was usually performed in front of the public. It was used to deter people from committing new crimes. A person was tied (or nailed) to a cross and left for a few days in this condition to die slowly thirsty, hungry and in pain. There were many variations of this method, where a person was tied to a wheel, a tree or even impaled. The first written records of this execution method date back to ancient Greece, where the worst killers and criminals were executed in this way.
