Self-Sacrifice Rears Its Head Again

I'm a little behind on Avengers Academy, so perhaps this has already been answered. In issue 21, Jocasta appears to have been attacked, and the body she'd been using wrecked. Quicksilver confirms she didn't download her consciousness into any of her other bodies, and there's no trace of her in their systems. So she's basically dead, and someone shut down the security systems from within, so it was one of them. Dun, dun, dun!

So how confident are people this was something Jocasta planned? She was talking about studying the cadets to figure out what they need, for the purpose ot "saving" them. She also there would be pain, though she doesn't specify pain for them or pain for her.

I'm not sure how her appearing to be dead is going to help the cadets. They could start questioning the teachers and their motives more, but they've been doing that ever since they learned the real reason for the Academy. It could be she feels Veil's departure has disrupted their friendship and she thinks this will bring them closer together. Whether that would happen because the kids decide to find her murderer, because they think some of the teachers suspect them, or because they feel they need to protect themselves against whichever teacher has gone round the bend. Maybe it's about the teachers, she wants to spur them into being warmer towards the cadets. Don't look at them simply as students, or soldiers, but as kids who need a friendly older presence. Especially with Justice and Speedball gone, the teachers seem less likely to be jovial.
