Take the original work, place the standard image for Darwin in the Throne of Judgment.
On Darwin's right, place representative examples of groups with high total fertility---Mormons, Amish, traditionalist Catholics, partriarchal extreme natalist Protestants and the like
On Darwin's left, place various examples of the converse--SWPL's with single or no children, reform Jews, and various winners of Darwin awards. Those who infamously lobby their own ethnicity to control its fertility while leaving other groups alone would figure prominently among the wicked. Those who worked against the relative fertility of OTHER groups and NOT their own would instead be on the right.
And above all, the figure of Darwin: Depart from me ye barren, ye never knew me.
Feel free to steal this concept if you like it. I've also been contemplating a 'Darwin's Inferno'. This of course is all satirizing the replacement of God with Darwin and the irony that Darwin, like the several versions of Baal in the Old Testament, loathes his followers far more than his nominal opponents.
