the problem is : you don't have to make an antagonist "with is sole purpose to be hated".
if only it was that, that would be okay, but rather, suzaku is simply illogic. he is almost a better "deus ex machina" than C.C oO
that's a shame, since having a serie with both the protagonist and antagonist as likable characters is really delightful... who just don't know who to cheer
(the usual "not so baddy" protagonist, like Zagat of Magic Knight Rayearth, or the Wolkenritter of Mahou Shoujou Lyrical Nanoha A's)
