Yuuki as well wants information! So she'd much rather capture than kill him (but would kill if necessary) and she'd opt for prison and a trial after! She wouldn't be down for a torturous integration though.

That said she has powers that can manipulate a person's mind, cause fear or illusions, among other things so she'd be willing to use that if needed. And she has a number of ridiculous abilities to help during the fight, etc.
