"depends on.............. the consumption of other living organisms to live? "
This is what I find so hard to deal with.
I watch nesting birds. Seeing a mother bird throw her week chicks out of the nest is heartbreaking. Not to mention the torture a poor frog goes through as she tries to feed her ravenous larger chicks since it's a little too big to fit down their throats....it's brutal. A mouse suffers a similar fate. And that's one bird, in one moment in time. Think of the billions and billions of suffering creatures because our world is based on predation. On murder. Completely aside from humans and han behaviour/suffering.
How can a benign god have designed such a mechanism?
