I was thinking the other day that since one of Batman's most pronounced enemies is the terrifying Scarecrow, and since Batman tackles the criminally insane, that fear is an important theme in the world of Gotham.
Well, the Joker is scary perhaps because he thinks evil is somehow amusing. The Penguin is scary because his behaviour and decision-making seem to resemble those of a crude animal.
However, the Riddler is scary in a very unique way, since, of course, he seems to believe that crime is a game of uncertainty.
While the Mad Hatter is also a Batman nemesis who believes that crime/sin/evil is an analytics contest, the Riddler specifically treats mischief/mayhem as an expression of confusion.
How much do policemen/detectives respect the notion that criminality can be confounding and that criminals can be confusing? The Riddler seems to make this message his mission.
That's why I like comparing the DC's Riddler to Marvel's Jigsaw and Doctor Doom, villains who typify criminality intrigue.
This thread is therefore a nod to the storylines, multimedia, and images/artwork that highlight the Riddler's religion.
