This. They're both bastards in different ways.
That said, I think it's amusing how much grief /a/ gives Suzaku. Especially about him selling out. What they seem to have forgotten is that Lelouch got the girl he loved killed.
Sure, you can defend Lelouch by saying it was a mistake but what would you do if your former best friend turned your waifu into a machine gun wielding woman on a rampage? Especially if you didn't know it was a mistake.
Anyhow, Lelouch was an egotistical, selfish, megalomaniacal bastard long before he screwed with Euphie. We just forgive him because he's so fabulous.
