Where as my own understanding of the strength of a tempering comes from the two Alisaie quest lines with the goblin and the 'ra child, in Ahm Araeng, where the former, whilst not concluded shows no breaking from the tempering of titan. And the latter whilst not described as a tempering by an entity referred to as a primal, did show a level of regaining its personhood.
Ga Bu isn't tempered. He is suffering from extreme dissociation due to the traumatic events he experienced. I.e. witnessing his parents' deaths and summoning a primal. There's a bit of ambiguity in the story around this, where Alphinaud briefly expresses concerns that the koboldling may be tempered but if that were the case they would have executed him ages ago.

Sin eaters are not related to tempering. Having your body's aetheric balance overwhelmed and corrupted by the pure aether energy of light is something entirely different.
