Yahweh, the Devil, and Job

[Esquilax]

Humans don't need pleasure and enjoyment?

They don't need donuts.

You're mistaking the object for the need it fulfills; technically, you don't need food of any kind. What you need is the chemical energy that food provides, so you could just as easily pump it directly into your gut.

The donut does double duty as food and a source of enjoyment, a psychological need that's better left filled, even if there are other ways to do so.
