Not neccessarily, a common theme in fiction is something can't be destroyed, but it can be changed into something that can, so perhaphs when souls are flayed to the point where they are no longer human, they stop being souls and start being demons, lets face it they share few if any simularities with any souls shown. They can't be absorbed, they are perfectly stable without a host, they posses incredible powers beyond that of most, and so on, all this suggests that when they become demons, they sease being souls, so they are no longer under the rule souls can't be destroyed.
