Frieza

Since Goku is moved to NPG, I wonder whether there is other cases. The first I think of Is Soichiro Yagami and Light Yagami deal with Mello (although Soichiro never knew Light's true nature).

Which PEs do you guys think did the most admirable things for obviously non-admirable and selfish reasons? This was just a fun little question I thought I'd ask, cause there are quite a few

For example, PEs who help the heroes save the universe in order to save their own skin like Slade and Frieza, or PEs who save humanity so that they can have people to rule over or give off the impression of being a hero, like BBH SpongeBob or GOW Zeus

Name any PE villains that have false redeeming qualities.

As the title says I want to know what was the proposal of pure evil made here (not on the villains wiki or on the villains fanon wiki) that took the longest to endend (dont care if the proposal was aproved or rejected). Out of courtesy you can say how time it took
