If you disbelieve the Abrahamic God, I then ask you, why would this be evil? What absolute set of values permits you to pass judgement on what is good or evil? If we're just all (un)happy random accidents, even actions that go against the rights of others can't be considered wholly evil. So what if something causes the suffering of humans? All of us, all of the people we know, everything the eye can see will simply vanish anyways after the heat death of the universe. So what is the absolute, unchanging and universal basis for calling something evil, allowing you to judge one's actions?
Now, if you do believe in Him, there's really no sense in trying to take our own warped sense of justice and apply it to God. He's the only one who has a complete understanding of every single thing that has happened and will happen, only He understands the reason for anything being the way it is. Try as we may, we'll never be able to see the big picture as He is able to.
