Um dude Meteion never turned on her creators. She believed she was helping them because that's what all the universe wanted, and that we ere just in denial. She was created to find the answer to life and instead found nothing but death, and suicidal yearnings. Aka Nihilism.

Because she was a super strong empath, that nihilism became a part of her sisters, which infected her as soon as she joined the hive. She became corrupted by it, but not in the sense of evil or wanting to kill to kill. She was bringing the universe what it wanted.

Even to the end she still desired not to hurt Hermes, she offers he come with her (of course corruptly after saying she'd have offered him a peaceful death) but when you redeem her she immediately is forlorn that she could not give Hermes the answer he wanted the answer he yearned for.

That's not turning against her creators. Also, I'd beg to say Meteion had more sentience than a typical AI. Everyone says she's just a familiar and AI, but so was Alpha.

She evolved passed that.
