What's he mean by "hurt in the right way?"

This is a bit of a joke. Dr. Doof here is implying that there is a "right" way to emotionally hurt someone, which he describes immediately after.

Why is "will be focused" used here? Why not just say "will focus"?

Great question!

The main difference is that the active-voice form ("will focus on") is more forceful and direct! Ex: My project will focus on ways that AI can improve medical care. = My project will be focused on ways that AI can improve medical care.
