The incel mindset is an elaborately constructed self-reinforcing worldview. Anything that might lead to self-improvement is cut off with hopelessness and self-loathing and thought-terminating cliches.

And Schneier's Law applies: "Any person can invent a security system so clever that she or he can't think of how to break it." Incels trap themselves in a fiendish bespoke prison they have constructed for their own torment. If they didn't direct that torment outward at people who don't deserve it, they would be pitiable.
