Did the Grand Inquisitor go back to the light?

In Season 2(?) we see the ghost od the GI who is now a temple guard again and even dealys the other inquisitors. Did he come back to the light side before dying or something like that?

It was addressed in Rebels Recon:

In short, Yoda was responsible for generating the visions at the Lothal Temple. That wasn't actually GI in spirit form or w/e.

Oh ok, thanks
