Destroyer w/King Thor plus hammer makes the armor more versatile, this what make it spite, if normal Thor was in it Thor will still, but King Thor it would be too damn powerful, HP DD isn't hurting or destroying the armor, HP DD would wasting it's time, the armor has unlimited strength, limitless stamina, the armor will hurt DD way before,DD can even dent it, which I doubt since the armor is fuse with fraction of the sky fathers powers plus the odin-force.
Spite!!!
