User blog comment:DarkUnknownWarrior/Pure Evil Proposal: SCP-610/@comment-14660436-20190825172107/@comment-14660436-20190825174650

I just told you: it's the ability to differentiate right from wrong. Any villain that qualifies as Pure Evil must be able to understand the concepts of right and wrong, but go out of their way to do wrong anyway. If SCP-610 is a thing that kills many people, but without having any understanding of right and wrong, then it's amoral and doesn't have a single shot at qualifying. The category is much more complicated than "it's a thing that kills many people horribly, thus it must be PE", you know.
