He's the one that set up the constant need to eat in the first place. Without the system he created starvation wouldn't even be a thing. He intentionally made the world so that millions of children would suffer from hunger and starvation every day.

"All-loving" my ass. He's a sadistic asshole who gets off on causing suffering and grief. Of course he doesn't exist, but how anyone could worship a being like that is beyond me.
