because satan is the bad one and god is the god one...thats just the way it works....yin and yang...you cant have one without the other

There probably is no god, but if you are talking about the biblical god, then yes, he is evil, he doesn't exist, but his character described by the bible is evil.

There are a few reasons why one could come to the assumption that the God of creation is Good. Firstly, the existence of pleasure. God has created means by which we can enjoy life. If God was evil, life would probably be at best dull. He has created good things, like sex, food, fellowship etc, which helps us to enjoy life. Some might argue that the existence of Pain and suffering would show God to be evil, but these things exist logically if one were to consider the biblical fall of man. Because man is now cursed by God, suffering exists in the world as a sign of his justice. Another reason you should consider is the form with which we are created. Man is not naturally born with deformity or disfigurement. God could have created us so that we would have a constant unfulfillable hunger, or have made us so that we bleed constantly and live in pain. The last reason is that God has revealed himself to man. An evil God could have chosen for us to flail around in the dark and believe that there is no meaning for existence (probably the darkest thought that one could have to live with). Ironically, many have chosen to believe this anyway.
