User blog comment:Kaestal/My theory of Savitar being the Arrowverse version of Cobalt Blue (And therefore Eddie Thawne)/@comment-24329997-20170415033804/@comment-24152851-20170418022410

Malcolm's train of thought was: Glades is a dangerous area, my wife and other innocents died there, nothing can be done to change that.

I did say he was an extremist, but he did conclude that it was the best choice. He ultimately wanted to save the city in his own way.

Joker is not like that at all, he kills people because it delights him, and at times doesn't seem to be aware there's anything wrong with what he's doing.
