This is the question that brought me to Wicca.
I believe in nature - it's neither good nor bad, it simply IS. Beauty may come from destruction, everything eventually balances out, we die and become part of the Earth, etc etc. (please don't confuse my thoughts as a guideline towards Wicca and/or Paganism)
I no longer practice Wicca. In this decade of my life I've been moving towards greater Jewish observance, and I still don't jive with the "Gd is good" notion, insofar as we define good. When I think about it, I'm not sure Gd has much to do with why I've moved towards greater observance.
Yesterday a friend asked me if I was a "glass half empty or full" type person and I said "the glass is."
seriously. end of question.
But is nature good? We just rented "The Happening," (nothing much happens in that movie) and I can totally jive with the message of that film, as bleak as it is.
Creation is a violent, destructive process.... often leading to to the creation of beautiful things/places. We can't call it good or bad because those are human definitions, and I do agree with PPers in that Gd sees farther than we do and thus acts accordingly.
I think that Gd doesn't really care what we do or don't do, but I find that mitzvot give *my* life purpose and direction, and help me frame my experiences in a way that makes sense to the human condition.
When I think about the scale of the universe, and our (my) place in it, I just don't understand a Gd who really cares about my issues. Esp when so much happens (and has happened, and will continue to happen) that goes against the nature of a 'good' gd.
