I think the ones that lived were taken for interrogation to see if they anything about Khaos Brigade and Diodora's connection to them. After that I think they were taken under... how do I put this... "Slave trading", so they they would be taken under someone elses wing and thier pieces won't go to waist.

That's just my guess.
