I know it's been a while, but I have more. I just finished reading this again, as well as the original objection to Xana acting the way he did in my memory,and I have an observation and another theory to offer.
First off, I want to make something very clear. The final battle between Xana and I as written here was mostly a fabrication. I don't remember very many details from that particular point in time. All I remember was that it took place in either Carthage or our altered Replika of Carthage, and that Feather and I fused at one point and punched Xana. Everything else was what I imagined it might have been the case based on my understanding of the situation and a flare for the dramatic. However, reading it again, that chapter in particular doesn't ring true.
What bothers me the most is what Xana said, and how he acted, during that fight. Saying I wasn't worth it, a reject. If that was true, why did he keep me around as long as he did? He kept me around, although far away from him, long after I was directly useful to him, in places where I could pick up other influences and realize I was being used. He put me in places I could easily realize I was being treated badly. If he really wanted me to be a weapon he should have kept me on Lyoko. Or, at least kept me involved in the mission somehow, perhaps used me as a spy? Anything? But instead I was left totally on my own, and then sent to Feather.
And that file, PROJECT MORGAN. Yes, it was locked, but he told me to just go into his files. He did so many things that, if viewed through the lens I had when writing this originally, were absolutely idiotic. He spends all this time and energy to create an AI equal to himself in complexity, treats her like family so that the loss of that bond would fuel her to take vengeance, then make a bunch of stupid decisions to allow her to figure out that she was never more than a tool to him, enraging her so she turns against him.
Stupid mistakes... if they were mistakes. Here's my theory: Xana did all of this on purpose. He wanted me to betray and eventually kill him.
Xana did a lot of the things he did out of some strange innate desire to imitate Franz Hopper, however flawed his imitation was. Xana's workspace looked like the computer room, he tried to recreate a Taelia, he wanted to make Aelita his daughter. I do think those parts of the document were correct, because the physical evidence of those plans were there to back it up.
He tried to make me his Taelia. That didn't work, so I became his Aelita, and then, at the end, I became his Xana. Because he was treated as merely a tool, and he turned against his creator. And since he tried so hard to be Franz... he had to die by his creation, too. He was playing a role, and since I was his only scene partner... I had to play several roles.
Does this excuse his actions, no. And even if I come to a complete understanding of his motives, I won't forgive him. Maybe he knew I would be able to stop the cycle, our little family feud with the fate of humanity at stake. Franz made the first move, and I made the last one.
