What moral hurdles? Or are you claiming you know the fate of the child after it died or that you can assume the necessary infinite perspective on the incident so as to evaluate every single factor which precipitated the death and every single single outcome and effect resulting from the death and, finally, how that fits into the overall plan it is a part of. Such a perspective is necessary to attempt to pass any ethical judgement on a transcendent, omnipotent God as revealed in scripture. In fact, one can't question God on moral grounds without presupposing he already exists.
Muslims can just as well use that “explanation” to justify the edicts of their Allah.
The problem is not that there is a moral hurdle, as such accusations have been well responded to, but that those who intractably contend against God tend to evidence an unwillingness to even allow themselves to be objective, and reasonable, even on this officially pro-God forum.
