The reason Sans is able to kill you easily with his 1 attack is because the "poison" damage you take in his fight is karma. It is based off of your actions. If you were in the pacifist route then you would only take 1 damage each attack and not lose hp from poisoning because it is karma based. Sans would not be able to win every battle unless the person he was fighting had done countless evil actions. Also I find it very unlikely Sans would stand a chance against Goku or Bill since he literally dies in one hit.
