Lelouch. Practical thinking, success and triumph are needs that sometimes turn into arrogance, I have grudges about social justice, and I absolutely hate those that seek to control others and misuse their authority. I have a conflicting moral compass between my morals and pride / desire to win, though I prefer to solve things my way, which are usually a form of idealism.
Also, emotions pretty much guide everything I do, even though I'd rather it not.
