After Being Bound to the World-Destroying Villain System, I Advised the Male Protagonist to Give up 'Saving the World'

If You Want to See Pure Self-Interest or Pure Evil, You Don't Need to Go Dark.

I want to watch content similar to "Killing Apartment: My Talents Are Infinitely Increased". As the title says, pure self-interest means that for the sake of strength, you can do anything, use any means, and be ruthless. Pure evil means doing evil purely for fun, without any need for compassion.
