What is the worst evil a scifi villain could commit against a planet?
blow up the planet and everyone on it
scar the skies to block all sunlight
planetwide orbital bombardment to glass the surface
planetwide bombardment to irradiate so nothing can live there ever again
trade blockade to inflict famine and pestilence
bioweapon that infects everyone and kills horribly
bioweapon that infects everyone and bars them from having children
bioweapon that kills everyone over adolescence and leaves the children to starve
enslave the population and divide them so that none will ever see another
shove it toward a black hole for inescapable time-dilated spaghettification
I don't care because these people are all fictional anyway
