Can you do that with the shitheads, scum and other bad yukkuris Yukarin? It would SURE help the world to be a better place for good yukkuriis, humans and other creatures.
Wouldn't that make a paradox? if Yukari can't take suggestions and get highly offended even by the most polite and nice suggestions, wouldn't that make her uneasy? so she would have to pretty much kill herself?
