I cannot sacrifice my intellect nor my own rationality for the presumption that beauty present in nature has any bearing on the existence of an interactive god. What is the difference between an undesigned universe and a designed universe? Nothing, as far as I know of and thus you seem to be pushing your biases to far.
In what way do we get ourselves into this mess. . . there are reasons held by those who seek to do things horrendous in the public or social eye as of now. This is more a job for psychology than it is the personification of guilt or evil that christians (Like you) seem to have prominently in many denominations. What would an uncorrupted person or thing be? How would you define corrupted without some subjective human personification or feeling independent of why these things happen in the first place? I would not claim they always corrupted because you haven’t given me a definition of what that would mean.
Should I say the universe is evil because it doesn’t favor humanity separate from its home. Or that the earth is good in a moral way because it allows humans to inhabit it. These are personifications that I will not abide by and neither should you.
Fourth, in what way are babies or animals innocent, this would also need a definition independent of how we should subjectively personify them.
Fifth, hope for mankind is a subjective issue that many will take sides from all over the board but is dependent on how the larger societal issues that have now been prominent continue to shape the direction of our world.
