I do not generally think of the natural world in terms of “good” and “evil/bad”. Nature is what is and we live in, and as part of, that. As Gecko suggests, everything has its place whether you believe that is due to divine planning or natural selection. Volcanoes and earthquakes are a favorite of mine. Yes, they have killed uncounted millions of living beings, including humans, over the time life has existed on Earth. And yet, if there were no volcanoes and earthquakes, if Earth was tectonically dead, what would happen? Mars would happen. With no active core, there would be no magnetic field. With no magnetic field, the atmosphere would be stripped away by the solar wind taking much of the water with it and the surface would be bombarded by cosmic rays and other radiation. Life, if it existed at all, would consist mostly of microbes in underground pockets deep enough to provide some shelter.
However, I would suggest that, on the balance, existence is “good”. Why? We exist. Life exists. There is beauty. There is complexity and a balance to existence. The universe is not inimical to our existence, even if it is not perfectly attuned to making that existence comfortable. Does this mean there is a God? I don’t know. It’s a matter of faith. If there is, I do not believe it would be a transcendent, supernatural Creator/Judge but more likely an active, present deity like that of process theology.
