The simple truth is that world has much more stuff that is not under control of humans.

The capability of humans to mess things up is tiny. We can kill ourselves in extinction, but the world will continue. With other animals doing unspeakable things to each other in the "perfect" world created by god.

As regards god, insofar as you admit that god is omnipotent and omnipresent, he has the ultimate responsibility for whatever he has created, including things that are not effect of human behaviour.

Your constant wish to absolve god of responsibility and to put it all on shoulders of humans is admirable.

It reminds very directly the way Germans idolized Hitler. After all, Hitler didn't kill a single Jew himself. However, for some reason we hold him the main responsible for Holocaust. This doesn't reduce the guilt of each individual Nazi, but there is a direct and clear responsibility of the ultimate leader.
