Rank superheroes by how tragic there rogues are.

I was watching trial eppisode of 90s Batman, and it got me thinking, who has the most tragic rogues. Joker is amazing but his acid pit is not as tragic as killer crock or mr. Freeze (a wildlyadoptedback story that gotbits start in BAS). Reverse flash is a great hater, but not nearly as the jester. So who's bad guys got it worse
