It is not so much that permafrost is good, as losing permafrost is bad. Permafrost keeps gases like carbon dioxide trapped within its frozen depths; when permafrost thaws, that gas is released, exacerbating global warming. Further, permafrost develops its own ecosystem which is destroyed when the permafrost is destroyed through thawing. The loss of all permafrost would mean the extinction of a lot of species.
