Soon, the day would come. Just as Lulu's misguided rebellion is at Britannia's proverbial gates, Suzaku will rise, not against the delusional Black Knights. But against the alien threat. Wielding the Sword of Akasha, the banner of humanity's hope of salvation, he will change the world with his own hands. Against an enemy with power beyond comprehension, that would make Lulu piss his pants and cower in his Knightmare, Suzaku will dauntlessly charge forward, cutting a path through fate itself. Because, Suzaku is now a hero. You can praise Lulu for acheiving that. After all, it was he that taught him strength, through Euphie's sacrifice. Now, Suzaku needs that strength, for the good of mankind. Betrayal, lack of ethics, singlemindedness, what does that even mean to a hero? Sure, he betrayed. Sure, he was misguided. However now he has to fight for the common good. Let Lulu become evil to fight the greater evil, or whatever pseudointellectual bullshit he's spewing. Real men don't need such weights on their mind, but a fearless heart and the will to fight.
