I have never understood why atheists ask the kind of questions that the OP is asking. To christians, god can never do "evil", what he does is always correct. You may think these acts are heinous, and I may agree with you, but we have to remember that good and evil are relative terms.
Because these questions get to the heart of some important issues.
The acts described are heinous. Any actual person coming close to doing these things would be rightly considered a most despicable villain. Yet the same people who revile Hitler for what he did, praise god for doing worse.
Remember theists generally don't have relative good and evil.
Also watching the machinations which zealots got to in order to rationalize away the problem really highlights how morally bankrupt they are.
Finally it brings home the common ground that no matter what you may believe about god, the one thing you can be sure of is he is not to be found in the myths of men.
