Well, I was about to post my share of Shin bashing but I think my thoughts more or less mirror DDBEN.

I will give Shinn the chance of redeeming himself though. At the moment, the only possible avenue I see that happening is through Stellar. Whether it will be her Death that will be the catalyst or something else happening between the two is yet to be seen.

Remember, during Gundam Seed, we probably thought it was the end of the friendship between Kira and Asuran when Kira killed Nicol (Blitz pilot.) And then came the titanic fight when Asuran killed Tolle and the two practically went berserk on each other. In the end, when they were both calm and quiet, they knew they were wrong in doing so, and so took another path so that they won't have to fight another again: by not taking sides in an unjust war.

A similar thing might happen in Destiny. How I am not sure, but as we all speculate, Stellar will probably be mindwipped and put in a Mobile Suit again and the two will battle once again.

Situation A: ideal situation
Shinn fights Stellar and somehow finds out shes in the suit but she has no memories of him. The two fight and somehow, both manage to destroy each other's suit. Shinn gets rescued by Archangel of all things and then maybe Kira can undo the rage. Crew of Archangel, who probably doing quite a bit of intelligence gathering, will rescue Stellar as well from EA clutches. Shinn breaks down on seeing Stellar again, then will mellow somewhat and start listening to other people for once/

Situation B: ideal situation for Shinn haters
Shinn DEFIINITELY KILLS Stellar, goes psycho, kills everything in sight, then gets sliced and diced by Kira, who will put him in a straight jacket and lock up in the Archangel so that he can be the star of the show again. [img]i/expressions/face-icon-small-happy.gif[/img]

Anyway, my point, for Shinn lovers, you all may be right that Stellar is Shinn's best chance for redemption. Otherwise, I agree that Shinn is a selfish spoilt brat that makes even Frey Alster look like Mother Teressa in comparison.
