Eva fell apart for me long before Shinji started to grate, in the lunacy of the EVA units themselves.
In a greater sense though, I feel a certain contempt for Shinji and the crew. They think they have it ****ty in their everyday lives. (****, the only thing that holds them together at times, I think, is their time in the EVAs; powertripping for those who think themselves powerless.). But the problems are comparable to ones that a lot of people go through.
They grated at a level deeper than most of you, I think. Oh-woe-is-me I can understand. Fatalism, of a sort, I can understand. Giving up, not even making the attempt, I cannot. I do not want to. Even at my absolute worst, when there seemed no point to it anymore, I got up and I kept going because that was the only option that made any sense to me. Shinji and the crew abandoned hope while they could still breathe; but that is not an attitude I wish to comprehend.
