Sooo, that means they are OK with letting those kids be in immediate danger...
Their lives aren't at risk, but they can still get beat up and left at the doorstep of death. They could even get mangled if the kidnappers decide that maybe they don't need two eyes, arms or something like that.
I personally wouldn't be inclined to piss off basically two living nukes.
Let's say that this experience makes those two realize that despite their value, the kingdom considers them completely disposable... and they decide to defect to another one, one that might actually treat them with respect.
I know it won't happen, because MANGA, but it probably should.
