Satan does not exist in the earliest parts of the OT before the Babylonian exile. Everything was attributed to Yahweh - good and evil.-cofty
I disagree the serpent was mentioned in Gen Ch 3, the rest of the bible refers to him being the father of the lie, Satan the Devil. It's evil to lie, hence the bible introduces evil straight away. In the first chapter of Job, satan has a conversation with God, the whole book of Job features Satan.
The point is do we belive what the bible teaches about evil. As I think that God is indifferent to us I likewise feel there is no evil force that cares about what we do. I do believe that people can be selfish, greedy, inconsiderate and hurtful. These types of people are evil. But people can also be the opposite.
