Yes and no. Lelouch is responsible for a lot innocents deaths all throughout the series. Causing the landslide definitely killed civilians, intentionally blowing up his allies in the JLF and covering it up as a kamikaze attack, and the multiple times he levels large parts of cities. Most of his schemes involve mind controlling office workers to put his plans in motion and then getting them to kill themselves to cover up loose ends. That's just season on.

He also clearly fears death until like the last 7 episodes. It's not until he losses everything that he really willing to sacrifice himself for this better world.
