Red Kyber crystals?

We now know a Sith's red blade essentially comes from a Jedi's kyber crystal that has been made to "bleed" by a dark sider-

So my question is- once a crystal has been corrupted, can it be incorrupted by a Jedi, or is it permanently tarnished by the dark side?

Talking about canon.

Depends what the writers want to make of it. I'd say yeah, a hint of its experiences may remain, but it can go back to exerting light side energies later. And in canon, students make their clear crystals turn a color specifc to them, so it would make sense as well.

And it'd serve the plot well.

In fact, Ahsoka 'healed' the red/corrupted kyber crystals she took from Sixth Brother's lightsaber... That's where the white crystals in her newer sabers came from:

Ahsoka stood up and unclipped her lightsabers from her side. She activated them, and Bail's office was filled with a soft white light, gleaming off the windows and reflecting the stars. The office was much smaller than a training room, being shipboard, but she did a few of the basic forms for him anyway. She would never get tired of the way they glowed. She hadn't thought she'd ever replace her original green ones, and she still had to finish the handles, but these were all right.

"They're beautiful, Ahsoka," he said. "I've never seen white ones before," Bail mused.

"They used to be red," Ahsoka said. "When the creature had them, they were red. But I heard them before I ever saw him on Raada, and knew that they were meant for me."

"You changed their nature?" he asked.

"I restored them," Ahsoka replied. "I freed them. The red crystals were corrupted by the dark side when those who wielded them bent them to their will. They call it making the crystal bleed."

Yes. Ahsoka did so to an inquisitor's saber.

The only good thing from Disney.
