Question about campaign (spoilers)

so cortana is evil now? Also why?

Is evil really the correct word? Crazy maybe? Misguided? Deluded perhaps? Idk about evil. Then again she did kill alot of people when awakening the Guardians…but can an AI be evil?

I don’t think it’s a matter of “good” and “evil”. It’s all just one big morally grey area. On one hand, her idea DOES bring about everlasting peace. On the other, it’s either subject, or be killed. And she DID kill a large amount of people bringing this plan together, so there’s that. She thinks that her way is the only way. However, I think we can safely say that the Librarian would heavily disapprove of her way, as she always truly meant for Humanity to claim the Mantle. The Chief obviously does as well, because her plan is basically the same as the Didact’s, but (potentially) without the eradication of the entire human race. Logically, she makes sense. Morally, not so much.
