Hello!
I was surprised to come across a thread of this type - I was under the impression that almost everyone in the community accepted Viktor as a stereotypical evil cyborg that is going to conquer the world with his evil machines and put everyone under mind control, thus making him the ultimate overlord. cough-cliche-cough
Fortunately, it looks like I'm not the only one that disagrees with that!
One of the most common things I've seen is people referring to anything Viktor creates as Battlecast. Which is clearly a very weak assumption. Nothing in the world can convince me that a genius of that caliber could create only one type of machines, and war machines, by that.
The Battlecast universe is indeed a very hard contrast to what the Evolution is supposed to be. The real idea was to release organic beings of deficiencies and allow them to "ascend", to put it that way.
Prior to his transformation, Viktor worked on a project that was meant to clean Zaun, the most polluted and reckless of City-states, and that says a lot about him. He was born there, and although he should have shared the Zaunite lack of care for safety, ecology and human life, he didn't. He wanted to help humanity. Hell, even his reaction to the injustice done to him contrasts Zaun's mentality. He wasn't distressed because he, let's say, lost a lot of money to Pididly due to his theft. He fell into a depression because he was let down and betrayed by the people around him. It was a slap-in-the-face to his trust in others. He was clearly naive, when he didn't see the theft of something that big coming, or even believing that a trial in such a corrupted City-state could restore his rights as the rightful owner of the intellectual property.
He started the Evolution with himself. Not experimenting on others first. The Evolution, I think, is actually his cry for help. He honestly wants to help everyone, by ridding them of the flaws that he pinpointed while he was in that horrible state of mind, during his depression. He wanted to prevent things like Pididly's theft from happening again. He saw the same flaws in himself. How that turned into "HA PUNY HUMANS, BECOME MY MACHINES OR PREPARE TO DIE FROM MY LAZOR!" is beyond me. I mean, I understand that sells the skins, but still...
Now, he's obviously alone, and that striving for perfection carries a risk of him straying completely into madness. But then again, what is considered madness? Or to put it this way: what if he wants to help everyone, even though some don't want to be helped? Helping them anyway is then considered a good or a bad thing? It depends on the point of view.
Although the Battlecasts seem like the doomsday machines, I think there's a possibility to look at things this way: remember the Void invasion? The one Kassadin keeps warning the world about? Well. What if Viktor stood up to that. What if he turned the Void creatures against that alien evil, and created the army to defend Runeterra and its future? If the Void devoured it, all of his effort in the Evolution would be for nothing. Battle Casts - it sounds like "cast to battle". Something from the outside forced them to fight, they were attacked. (okay, I see many will say "Viktor forced them to fight" but bleh) And also, Void creatures also are made of flesh, the quotes could be referring to them, perhaps. And what about the Resistance movement? What if some people interpreted the creation of the Battlecasts as a threat, and that Viktor was aiming to turn them against humanity? What if the Resistance attacked first? That would be a very serious plot twist. I realize, probably with very slim chances of happening, because people like cliche's at the end.
I've tried to write more about this here, but I'm not sure if I conveyed it exactly the way I wanted, so I'll be refining it in the future.
And here's for the end, something I drew to continue the story of the Battlecast Skarner
