People be full of darkness. It easily corrupts the soul if there is no guidance from a source of light. It is much worse when your elders enable the darkness within you to grow unchecked.
A purifying is needed! If you can't purify the darkness... The important job of executioner is required. Ahh. Too bad this world we live in instead thinks caging criminals for various spans of time is helpful. The prison system is so costly and unhelpful.
