Although I agree with most you say on them being fascist asshats, there is not the slightest evidence Edison had anything to do with the killing of Topsy.
The killing was done by her handlers as they wanted to get rid of her, they could not handle her anymore after an incident with her original handler. The film of the killing was released by Edison films yes, but Topsy was killed a decade after the war of the currents, and Edison wasn't even in charge anymore of the company after the merger with General Electric.
He wasn't present during the electrocution of Topsy, did not have any electric business anymore, and again there is no evidence whatsoever that he was involved.
But Yeah, fuck 'm all, except for Topsy, may she rest in peace.
