His sheer will to kill you, and his karmic retribution is all because of your actions. In a way, you're fighting yourself. You made him so strong. I also believe that Papyrus CAN do the same things as Sans can based off of this dialogue after you spare him and abort your genocide route. 'You would surely have been blasted to...' Blasted, implicating he does indeed have gaster blasters. He is waay too nice to use them though. I am not sure about Papyrus having Karmic Retribution though.. Basically, his stats show he is indeed the easiest boss in the game, but his fight is all a result of your actions.

At least that's what I thought when I played through the game. Correct me if I'm wrong. This is, in my opinion, the best way to explain how Sans is simultaneously the easiest and hardest boss in the game.

He isn't actually very difficult to beat in reality, practically anyone in the underground could defeat him if they wanted to. However, your actions do have consequences, and doling out karmic retribution where its deserved happens to be his forte. After all you, as the anomaly, are the only person like you in the underground (It was Flowey previously, yet he understood how difficult it could be to beat him under those circumstances).

I also believe Papyrus can do the same things that Sans can, possibly including the dodging aspect (but would not do so to make it a more fair fight).
