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?
