It's unclear what Gamma was actually trying to accomplice, whether he was trying to free the animal inside of his brothers or simply trying to free the E-series robots from the torment of being pawns of evil. Sonic X seems to take the latter route as Gamma does not destroy most of the E-series and merely de-activates them. If that's the case, Gamma was essentally going on a suicide mission, even if he was at peace (if robots can be) afterwards, it's still tragic.
