Can You Really Say Evil Is Just a Privation of Good?

Questions about whether one can legitimately say evil is a privation of good, how the Bible can say sin and death entered the world at the fall if angels rebelled before man, and why God would judge Israel with a famine so great they would eat the flesh of their children. Saying that evil is a “privation” is simply wordplay. How is the privation of a thing not creating the result of that privation? If one is denied oxygen, he will die, but you would blame the one denying the oxygen for that death. Scripture says sin and death entered the world at the fall, but didn’t angels rebel before man? Wouldn’t sin have been introduced then? Why would God judge the Israelites for sacrificing their children to idols by pronouncing upon them a famine so great that they would eat the flesh of their children?
