Maybe not dangerous, but powerful in living. Besides, in the lost soul fight, Sans does not use his full power. Papyrus can use psychokinesis - he turns souls blue, just like Sans, and he floats once, probably because he turned his soul blue. His special attack is hinted at being a gaster blaster. He just doesn't want to kill anyone, therefore he isn't dangerous.
