It's not that I hate geass or something since I just realized this much much later after it aired. I partly agree with you about Clovis. I don't see that much of a justice on Lelouch's decision to immediately kill him.

Although yes, he's got that attitude that makes you want to kill him...

I see Lelouch immediately killing him off if he's a mortal enemy of some sort, but Clovis is not so... After that threat he posed to Clovis, I don't think Lelouch should have killed him right off the bat. Then again, maybe that's an adrenaline rush for Lelouch for finally gaining some power to advance his plan of revenge.
