what can I conlude is that lelouch act on revenge but still using reason (not repeat the tragedy as the main reason) while suzaku also act on revenge but lack of reason (for the drug use only) and seems the type that would do anything for that. too blind and act on his feeling only just like s1 . He thought or to be more precisely he's convincing himself that lelouch killed shirley to make himself looks like the "good" one. He didn't reliase that he and lelouch are the same just like image in the mirror. well if he reliase it he might turn nuts.
