Maybe, but one thinks there would be other options. I mean, they did win. Tribe A has been defeated. Why not let them go in peace after they lost? After all, they are likely to die without food or water in the wilderness anyways. I mean, in real life if POWs are captured during an attack, they are either sentenced for crimes, traded back to the original countries for POWs of their own or eventually let go. After all, you can't hold every member of an army responsible for an attack on you.In the ensuing conflict, tribe B wins. And has prisoners of war. And has to decide what to do with them- kill them, let them have what they wanted in the first place or find some compromise where the POWs live but don't just get to walk away after killing a bunch of the tribe. Maybe make them make up for what they've done somehow- make restitution.
Sounds a lot like justice... and one viable option for a tribal society with no tradition of jail or imprisonment in this situation is to enslave tribe A.
Not sure I understand the provision on "no tradition of jail or imprisonment". That's like saying "What if there was a society with no tradition of jail, imprisonment, slavery, or mercy? Wouldn't that mean the only option is to kill all of their enemies?" Just because they don't have a tradition of jail or imprisonment doesn't mean that isn't an option still.
It sounds like this is simply justification to enslave your enemies by saying "sorry, we don't believe in the other options". The reason you don't believe in the other options, however, is that you are evil.
