>>2329355Kira was never killed, we got that "lol, plot device" at the very beginning of the episode that followed that one, so it wasn't on the plans to Kill Kira, though your idea of Shinn realizing his revenge was pointless and stuff and grow up from it could had still worked since he would still think that Freedom was down and Kira wouldn't show up again in front of him until some episodes later. It kinda proves that at the end, Kira wasn't the real problem, but the way Fukuda and Morosawa fucked up the directing and writing so badly.
Though the damage was already done from day 1, and just keep on accumulating shit until it become an epic shitfest.
At the end, the only way to have GSD fixed is to rewrite it from 0, because killing of Kira, Shinn, Athrun or anybody like that, at the end would be pointless are meant as a scapegoat for the real problem the series had, horrible writting and directing focused on market over telling an averagely good story.
