Also, deflecting the Emerald Splash easily is pretty evil, it's breaking Kakyoin's dignity, and shaming people to death is the second evil thing that someone could do, because shaming can be through verbal or through pranks.

So, in terms of main antagonists, DIO is the most evil main antagonist in the whole JoJo universe. No one can just deflect the Emerald Splash, god dammit.
