User blog comment:The Crazy Terror/PE Proposal: Crimson King/@comment-5032898-20190829052730

No, he seems more like a made-of-evil shadowy figure behind the dark, lacking active actions and moral agency. In fact, both in Insomnia and The Dark Tower series, Crimson King only gives out orders to his minions, while his subordinates like Atropos and Randall Flagg all have much worse onscreen crimes than him, especially Flagg who has his own agenda in destroying the world.

As for comparing him to Pennywise, well, the Crimson King is a rather generic doomsday villain in comparation since Pennywise induces fear on purpose, through all kinds of methods that are much cruel than the Crimson King. In addition, even many human villains does much worse than the Crimson King (e.g. William Wharton).
