It didn't take any convincing at all for both Vorden and Raten to be in on the plan. Vorden hated the idea of anyone going through what they had to. Maybe Quinn's righteousness for a change in society was rubbing off on him.
As for Raten, he was happy to see the whole place burn and was imagining the look on Hilston's face when he left the place with the kids. Where would they go, well, he knew Quinn would accept him and the kids if he asked to. They could probably survive on the large spaceship for a while.
The problem was, doing this meant they would be enemies of the Balde family, which would make it, so Quinn had another large target on his back. Vorden and Sil just didn't want to do that to Quinn.
Instead, they would go to their own planet and hide it out for a while.
