But all life does NOT rely on the violent death of other life in order to survive. And if some life survives without the violent (or otherwise) death of other life, then the possibility is there that all life can.
What is an acceptable amount of violence in nature for an all loving deity to create? Some things are vegetarian, some live off of waste, some live off of light. But then the rest rip out throats, hunt the young and the weak. Or lay their eggs inside the living so the larvae feast on the internal organs, saving the most vital ones for last to ensure the host survives as long as possible. If you think life is designed, then violence is built into the design of an incredibly large percentage of life. Did god not create the parasites? Why would something so specially designed to malign and kill in such an elaborate way suddenly be changed to be peaceful?
Your first paragraph is what I was talking about, the apathy. These questions aren't important, as long as you believe in the loving part of the story. But what you don't realize is that love isn't a deity, it isn't some universal law or force. It's you. That compassion is yours. The universe is a cold amoral place, the earth is a chaotic violent sphere and it's digesting you. It's great to focus on love, but don't try to say that it's built into the universe or it's a defining characteristic of the way the earth was made, because you won't find it there. You find it in yourself.
