Answer: Adults may be physically stronger and more skilled, but that makes them harder to capture and more dangerous to their captors as they would resist and attempt to escape. Children can be indoctrinated to their cause and are more easily intimidated into being compliant. If they're killed, it's easier to kidnap more.
