I don't know what all the fuss is about - it all seems pretty clear to me.

Frisk can only SLR because they have the determination due to the whole "player-controlling-them" stuff. Flowey can only SLR because he's had determination injected into him.

There's no evidence in the game that Asriel or Chara had the determination required to SAVE. Chara even outright says 'My "human soul". My "determination". They were not mine, but YOURS', meaning she had no determination of her own.
