According to the Disney canon, Kyber crystals are inherently resistant to the dark side of the Force, and dark siders must bend them to their will for them to work in their lightsabers, creating a bleeding effect which is why all dark siders have red lightsabers.
If that’s the case then Anakin’s lightsaber should have stopped working because it would have sensed his turn to the dark side in ROTS, or at least should have turned red due to Anakin’s dark side influence, but no, it keeps functioning as normal when used for very obvious dark side actions like slaughtering children.
That’s an excellent point. Trying to force an explanation when none is really needed has just created more inconsistency. I’m not opposed to the idea of the kyber crystals having some connection to the force, but they way they are going about it just isn’t very good or well thought out.
Like, I’d be ok with them having a kind of presence in the force, like a vibration or something (crystal vibrations are something that plays right into the mysticism angle). I mean, that idea works well with the scene where Chirrut senses Jyn’s necklace in Rogue One.
But having them be semi-sentient and Sith having to bend them to their will to get them to work? And then “bleeding” in response? It’s just dumb.
It’s true. All of it.
I don’t know why the writers just couldn’t chalk the different colours up to tradition. I’m sure in the real world, cardinals in the Catholic Church could wear silver robes with green sparkles if they so wanted, but they don’t, and it’s not due to any convoluted practical reason.
