Questions: Religion & Spirituality

Of course Satan's job is not only to tempt humans to sin but wanting us to give in to sin and not flee from him or be able to resist his temptations.

If we as creatures of God were given free moral agency, the ability to choose sin or righteousness, then why is Satan necessary? Of course people can influence others to sin even though they don't make them sin. Is Satan the same way? Satan doesn't make us sin but he entices us to try to sin because he hates God so much.

If we can choose to sin on our own without the influences of Satan, why is he needed? If mankind truly has the free moral agency given by God, then man would know whether they want to sin to live righteous. If Satan influences us to sin when we normally wouldn't have, then Satan would be needed. But is this the case?

Please share your Satan influencing us to sin thoughts!
