But who says we deserve better?

We don't cause pain to 'lower' beings than ourselves*, we use them practically to our benefit but we do not cause them unnessecary pain. Even if a dog has killed a little girl or something horrific if we are able to do so we will take down the dog in a non lethal manner.

So collectively we think animals deserve better, and we are much more moral than the animals**

So humans are more merciful and forgiving than God, by the sounds of it yes we deserve better...

*Im thinking collectively and legally...

** In that we will fight our natural instincts if its the wrong thing to do (steal food from a baby) whereas an animal would mostly (if not... other stuff )
