Basically you still committed the same level of sin by making the fight worse for yourself, and in such a way that pisses off sans (if you see the impossible ending). It may not be based on LV, but you still killed everyone, even if you have the lowest LV possible. And if it really weren't because of sins, then why does it say messages like "you feel your sins crawling on your back" and stuff like that?

Think of it this way. The name of the effect being "Karmic Retribution" may not be canon, but the same thing goes for the name "Omega Flowey". The game named him "Photoshop Flowey" but barely anyone calls him that and just fandubbed it Omega Flowey.
