It's an easy get out clause for them which is why I asked about children having diseases which are certifiably not man-made. Only 'God' could have decided that these would exist so he is responsible for creating these diseases and allowing innocent children to have them, suffer from them and potentially die from them.
The only way that it isn't God's fault for things like leukemia is if they blame evolution for f**king up our DNA, which, ya'know, ain't going to happen.
