I rewatched the whole scene and the dialogue is: "if a human ever comes trough this door... could you please, promise something? watch them and protect them, will you not?", I see no mention of "another". But even if it was there, it could mean that other humans were there and died, it doesn't necessarily means that Sans killed them, but that could be the case as well...

But the thing I don't understand then is, if he had no problem killing previous ones, why would Sans stop at seventh which is final requirement for breaking the barrier?
