I honestly see no problem with this new Camille lore and the possible connection to Viktor.
Granted, I am not an avid fan of Viktor's lore and personality, and I despise his gameplay, but as someone who great enjoys "gray" characters and stories, I don't see what the issue is.
The only thing shown was some cult that likely took his ideals and then pushed them to the extreme and is using a "divine" figure in order to keep those ideals with an iron fist. All I see are extremists. Much like the difference between extremist Muslims and non-extremists (Then again, people aren't very good at seperating the two anyways), this cult seems like extremist. It has not been confirmed that Viktor has knowledge of this, much less confirmed if he completely approves of this or not.
I repeat, all I see is a cult that has taken Viktor's ideals to an extreme, not Viktor carrying out his goal through a dark cult.
Over-reaction much anyone?
