In my opinion, only human are good or evil, not God. Assign this human things to something that we dont know if exists or not, is an error and a way to avoid our own acts.
God created this world and man. And people themselves make this world good or evil. It all depends on who is treating different things and situations. And there are more good in this world.
And I always thought that God created only good things on this planet. How can he create evil? What for? I think that all evil on the planet was created not by God.
