Vonnegut's Philosophy on Voluntary Monstrosity

From Kurt Vonnegut’s “Breakfast of Champions” (1973):

But he learned from his encounter with Dwayne that he was alive enough to give a fellow human being ideas which would turn him into a monster.

Here was the core of the bad ideas which Trout gave to Dwayne: Everybody on Earth was a robot, with one exception - Dwayne Hoover.

Of all the creatures in the Universe, only Dwayne was thinking and feeling and worrying and planning and so on. Nobody else knew what pain was. Nobody else had any choices to make. Everybody else was a fully automatic machine, whose purpose was to stimulate Dwayne.

Dwayne was a new type of creature being tested by the Creator of the Universe. Only Dwayne Hoover had free will.
