I am THE SPECTRE. In life, I was police detective Jim Corrigan. In death, I have been charged by a Heavenly entity named The Voice to eliminate all evil from the world. Not bound by humanity's notions of law and justice, I am free to punish criminals in ways you might deem "cruel and unusual", yet at the same time fitting in a deeply ironic fashion.
Yes, irony. For one such as me, punishing evildoers in ways that evoke their own wicked methods and modes of operation is a point of professional pride. A "calling card", if you will.
Take my punishment of Peter and Eric in AdventureComics #432 (1974), for example. Hair stylists by day, these brothers and their supermodel associate were assassins by night for corrupt businessman Maxwell Flood. After I preyed upon his guilty conscience, an unstable Flood fled to Peter and Eric's salon and into the choking embrace of Eric's hair dryer...which begged for a fitting salon-themed punishment!

Ironic punishment. Not for the faint of heart.
As for Peter, I turned him into a pile of sand.
Yes, not especially ironic...but satisfying nonetheless.
