No, it's not a dead point, the point is that you made up something that had only ONE thing going for it, Neo/Mwu's expendability, which I don't disagree with you on- but the rest of the variables which should be utter common sense to you should tell you that there's not a point in bringing it up- there is NO possible way that Neo/Mwu could have gotten into Freedom in ANY scenario, and your stubbornness to admit that is appalling.
You're God-modding Kira again. As a pilot, I'm sure he could have done enough of a deflection to not get himself killed- but the notion he did it for anything other than self-preservation is ludicrous! How the heck can you honestly say this was going on in his mind: "Well, I can't avoid this attack, but I can disable Impulse to where they can't see what happens to me, and I'll be able to get away with the AA." Shinn gave Kira little time to do much of anything but react, especially with Kira's attention split b/w the AA getting shot up, and Impulse going at him full fury.
Beginning of episode 33, before the OC, Shinn puts Stellar's body into the lake. He cries for the loss, and he also, while crying, apologizes to Stellar for not protecting her, for not keeping her safe. THERE. PROOF that he does at least feel partly responsible.
