But that's why I think Lelouch is a better "Dark Messiah" character than either Ozymandias or Light Yagami (Death Note); Lelouch's mistakes and emotions made him feel more human and relatable than most "Dark Messiah" characters. Also he had an actual motivation to do the things that he did as opposed to other characters of his archetypes.
That's how I see it anyways...
Also, if you're using R2 as basis for him wasting personnel etc, keep in mind that R2 was NOT what the creator had in mind for season two. That was a snafu caused by the tv station deciding that the series had gotten a sufficient fanbase to qualify it for a move from midnight on Sunday to a prime-time slot. Which meant they had to restart the series essentially and re-explain everything they'd explained in the series up TO that point.
Besides - would Lelouch be so interesting to watch if he were perfect?
My point isn't that Lelouch isn't that smart - I consider him the Patron Saint of Magnificent Bastards - I'm saying that in this particular scenario, he was asking for it. Diabolus Ex Machina.
As for Ozymandias... personally, I never liked the guy. He's smug, he's competant to the point of being uninteresting, and the idea of word peace stemming from the fear of being arbitrarily wiped out at a moments notice doesn't make much sense. We already have that possibility. They're called asteroids. Look at all the world peace we got.
Now, I'm by no means saying Lelouch is perfect. He fucks up several times. Some of his actions are outright stupid. However, I personally am of the opinion that Zero Requiem was so fucking awesome that he qualifies as the Patron Saint of Magnificent Bastardry.
Xanatos is the Master of Xanatos Gambits, of course. He's fucking Xanatos. (Admittedly I should finish watching Gargoyles before saying that. I stopped watching out of boredom of the globetrotting episodes.)
