I don't know the Buddha's teaches on this specifically. However, I would think if the only way for them to progress away from suffering is to allow them to suffer more (temporarily) then that is what should be done. But I think this should be a last resort. You should explore all your options for helping them. We should always try to avoid causing more suffering. And even in the case that you allow them to suffer more the end result is less suffering.
