My benevolence is unquestionable. Do you know how many potentially cataclysmic asteroids I have destroyed and swatted away from my planet over the past several thousand years? ... Three!

[People had been more afraid of those asteroids than they were of Aku and Aku simply couldn't have that. Nor could he have something other than Aku destroying his planet!]

And how many Rulers of Earth do you know that have theme parks? When all is said and done, I will grant you a free day pass to Aku World and then you can tell me who is benevolent.
