As a kid he murdered his father on an impulse, which resulted in Japan surrendering: people covered up for him, told the world his father had committed suicide and thus he felt guilty about it his whole life. He enlisted the military not because he wanted to change anything but because he wanted to be punished, he wanted to die in service (sacrificing himself) because he was too much of a coward to kill himself. He wants to help people not because he sincerely wants to help them but because he wants to make it up for having murdered his father, he wants to "save his own soul".
Ultimately, Lelouche's geass on him makes him an unstoppable killing machine by balancing his reckless deathwish with imperative of staying alive NO MATTER WHAT. And then he helps with the Zero Requiem and lives the rest of his life as Zero not out of goodness but as penance for all.
For some reason the character clicked with me, I found him the most interesting character in the show by far.
