I understand he's a guy who thinks it's best just to play by Britannia's rules and he has high morel standards. But what the heck was with him saying that he should turn in Zero after he saved him? He does show that he's grateful for what he did but he probably thinks he should do it instead of joking. It's not like Clovis didn't have blood on his hands either. I get the idea that anyone can be saved but violence begets violence. Was Lelouch wrong for killing Clovis? I think you can agree he was because Clovis wasn't armed when he killed him. I'll say the circumstances behind his death is sad, being killed by his half brother, but that doesn't change his past actions.
I know some people hate Suzaku. I never really put too much thought into what motivates him in the past but I think now's the time I take a deeper look at him.
