I've been exploring the main philosophy of my villain and I actually found a expanded version of antenatalism witch is called Efilism.
Exploring this philosophy I've realized that it's not actually that extreme it's a natural conclusion that liberals and anyone left wing would come to if they're actually smart enough to go down the full path of utilitarianism. I remember watching a philosophy video and reading a paper that discussed how the left inherently views life as painful and something that needs to be fixed while the right inherently views Life as a gift and something that needs to be cherished.
I think I've come to the full conclusion that it the left and right of politics it's two fundamental beliefs on the existence of life just apply to different social issues.
