Yes it worked in the show, but again, total arsepull, and we don't know for how long after. We basically see the immediate aftermath, and it's typical human nature that would lead us to fall back into chaos. See the First World War - we thought it was the war to end all wars. That was, until the second one.
It's important to me here to speculate beyond what the show presents us with simply because Lelouch was identical to me in his ideals, on top of the fact that it shows us why Light was better. I'm not so much bothered by the fact that he died, as I am by the fact that he set it up so that he would die - if the world had become a better place and he had gone down against his will, I would have been satisfied.
His plan was to make a better world. He did. Look again at the very end if you need to. Colin said it. As for as the show's concerned, that's that. The show told us the world was better, and that's all we have to go on. Sure, of course there's no guarantee it's stay that way, but there's nothing given to say that it would fall back into chaos.
I don't usually speculate about could happen after-the-fact. I go with what's given.
But it doesn't make sense because it's inconsistent with Lelouch's general behaviour and attitude for the rest of the series. He specifically wanted to take charge because he thought he could make the world a better place, he gathered the world's hatred upon himself, but he was generally smart enough to realise that killing himself would not mean that the world's hatred would die with him and that the world would suddenly become a much more peaceful place - no, after Adolf Hitler died did everyone suddenly become one big happy family? Of course they ****ing didn't.
The fact that everything Lelouch did was wholly consistent with my general line of thought right up until the last fifteen minutes, to me, is proof that it was a total arse-pull. The writer was making it up as they went along, they even admitted this, and the ending makes no logical sense - Lelouch having generally been logical before that point again just annoys me.
If he did that, he'd be hurting the people the wrong way. He didn't want to fight against them. He needed a target for the hatred (himself), and someone (Kururugi) to lead the people towards that (the Britanian Government). They still have to fight against that, and Kururugi's leading them that way. But like I said, Lelouch didn't want to fight against the people, just take in thier hate.
It all makes perfect sense to me.
That's why Kururugi is Zero. He's there to do what Lelouch was doing, to take his place. He can't go back to being Zero, so someone else had to take his place. Plus, if he stayed alive, all that hate would eventually reach a boiling point, and terrorism would start against him.
But honestly, the anime leaves us with a 'happy ending', and that's all we know. Unless they make a third season, there's no way to know for sure if everyone would turn on each other again or not.
Yes, he's right, which is why he should have kept himself alive - in order to maintain that focus of hatred on him. As soon as he dies, people will hate his memory, but they'll be free to turn on each other once again. Everyone set aside their differences to complain about general oppression.
Except that at the end of the anime, he said that the blame for all the bad and hate, was directed at him as the emperor. He still gets all the hate and blame, even in death. Also, Kururugi became the new Zero to combat the injustices, and guide the hate. (Really, no matter what, there's always going to be 'petty little hates' regardless of what's happening, or who's in charge. There's no way to obliterate that.)
It was different in that before, it was always setting himself up to be in charge because he knows better. Here he's not only leaving the world for the hands of someone else, but in having himself killed, he's destroying himself as an avatar of hatred and thus leaving room for the other petty little hates to come along and destroy society from within. As long as he was alive to hate, people would continue to focus their anger on his oppression rather than each other.
If anything, he made more sense. I admit, he was a cooler being a psycho (), but I find nothing wrong with it. Sure, dying isn't something you expect him to do... and yet that's everything he ever did. He was always doing unexpected things, and this was really no different.
