For me the worst part was killing Papyrus, which is a common opinion. Just seeing him accept you after all the horrible things you've done, and then you just have to go and kill him.

But, of course, even then he still thinks you could change. You just killed him and in his dying breaths he tells you he still thinks you could be a good person. You, player, are a complete asshole, and you know it.

Anyway killing Flowey and Undyne are also very sad moments, and so is Sans, just to a lesser extent.
