Why did God make the angels? (and other questions from a doubter)

Here are four questions from a concerned Christian whose loved one is doubting the faith: Why did God create the angels if He knew they would fall? Why did God put the tree of the knowledge of good and evil in the garden, if he knew Adam and Eve would eat it? If God knew everything that was going to happen, does that make the incarnation, life, death, resurrection, and ascension of Jesus plan b? Does doubt mean that you've lost your faith?
