Are you implying god *can't* create a world where there's good without bad? You seem to be underestimating 'eternal power' a bit.
There's many things God can't do and it makes perfect sense. Eg., God can't lie. "Good" is a direction, so to create a "good" necessarily implies creating the possibility of bad.
So, theoretically speaking, what did God do that's wrong? Create a world where "bad" is possible? (not trying to be argumentative here, I want to hear your point of view)
I don't think so - the assumption was that as a perfect being God doesn't commit "wrongs" and "wrongs" are required for the feelings of guilt - sociopaths don't feel guilt.
Yet, they do not feel guilt for it which is what makes them sociopathic. God doesn't feel guilt for what he does regardless - whether Gods actions are interpreted as "wrong" or not.
