I’ve never been a great fan of abilities being categorised either as darkside or lightside, I prefer to think that both dark and light are moral interpretations of the same thing.

So lightning is ‘darkside’ not because it’s on the darkside powers level up path, but because it directly harms and tortures people. Whereas a mind trick is ‘lightside’ because it’s an alternative path than violence.

Similarly, ‘preserving those we love from death’ is darkside insofar as it’s an act of fear of loss, an intervention against the natural order of things. When baby yoda used it, I put it down to his naivete, but when Rey did, it felt like an attempt to make force healing less inherently dark, which I didn’t like.
