A Wendigo is Supernatural as well, but can be killed by fire.

No angel has ever shown the ability to destroy a town, so that's no evidence. Even Lucifer, an archangel, asked Death for help to destroy Chicago.

Castiel was hurt by falling down from a building on the top of a car, so yes, physical things may not be able to kill them, but are able to effect them as well.

Jesse, who never showed any feats beyond the level of an archangel, destroying a whole galaxy is just to ridiculous.
