I think our understanding of unfairness in the world is mostly relative and based on our imagination which is based on our experiences. Even if the world were objectively better we would just adjust our expectations for happiness and fulfillment upwards and still suffer accordingly. If the average lifespan could be increased to 1000 years, then when someone dies at 316 folks would still say: "What a shame, she was cut down so young. She had so much of her life ahead of her". If no one ever got diseases like cancer or multiple sclerosis or Huntington's then atheists would use paper cuts to question the mercy of God.
I also think it works in reverse. If one of those bug species, where the female eats the male after sex, evolved into intelligent and sensitive creatures with technology and civilization but the same basic means of reproduction, they wouldn't necessarily be more likely to doubt God's mercy. They would probably just accept that violence was a part of their life cycle and move on. (Consider how, even for us human beings, in certain parts of the world family life is marked by violent rituals and customs, often with religious sanction).
