>>3196604>>3196677At that point in the story she just hates machines, wants them all dead, and doesn't really have any stakes in anything anymore after what happened to her. She was betrayed by Yorha so she hates them, and machines killed all her friends
and lover so she hates them too. I think she cared more about blowing up the tower as a middle finger to the machines than anything else. Mentioning the human server was probably just because she didn't care to fight 9S, but that's just my guess. It's been a while since I played the game and Ina isn't spending a ton of time reading all the lore dumps. I'm curious if others have better answers, because A2's characterization compared to everybody else was the weakest thing about the third act of the game.
