Is God willing to prevent evil, but not able? Then he is not omnipotent.
Is he able, but not willing? Then he is malevolent.
Is he both able and willing? Then whence cometh evil?
Is he neither able nor willing? Then why call him God?
— The Epicurean paradox, ~300 BCE

But, What is Evil? What is omnipotence? and What is God? What would it mean to say that God is Willing? These terms come from primitives with an extremely limited scope of understanding. You may as well be talking to your dog. And that's still true with most people today, except that people today have chosen to be idiots, rather than actually learn about the world. It's their loss, but they impose their ignorance on the few who revere Truth.

Hmm, looks like an equation to me.

Is God willing to prevent evil, but not able? Then he is not omnipotent.
Is he able, but not willing? Then he is malevolent.
Is he both able and willing? Then whence cometh evil?
Is he neither able nor willing? Then why call him God?

I don't see the logic. What would exclude an omniscient, omnipotent god from being benevolent, etc. I think Epicurus had the better argument.

Logical conclusion.
