How would you address the Joker Paradox?

By that I mean to say the fact that the Joker is supposed a crazy person who is only slightly more intelligent and athletic than average, yet he is somehow able to rack up a 3-digit kill count and evade pursuit of a character who is regularly put over as a god killer.

A few options
A) Joker was really supernatural all along
B) Make Joker actually as competent as Batman + crazy (This might not be an option anymore because of the Batman Who Laughs)
B) Joker is actually being supported by someone who profits from his antics (i.e. take the meta reason for his continued to survival and make it text)
C) Batman isn't really that that good anyway, otherwise why would he have so much trouble with a murder clown?

Other ideas are welcome. I'm curious as to what would be the easiest sell to the public.
