@Alan McDougall,
so xris, you basic argument is that because anything bad can happen, God must be responsible, and there are bad things, God created them, therefore God is bad.
Is that it?
The notion of humans having free will and being able to choose their own destiny, is a really important aspect of the whole of Western religious doctrine. It speaks to the nature of freedom. If nobody had any choice but to 'do good', then goodness would have no meaning. In fact you could go further and say that the possibility of error, of evil, is an indispensible aspect of the whole picture. Unless the Good can be freely chosen, and chosen, not out of guilt or fear of the consequences, but because it is the very best thing that can be chosen, then what is it worth?
