Without the possibility of suffering, there is no love.
That is the measure of love - how much suffering one is willing to undergo for another human being. The little girl is not the only one suffering; her parents and friends are too. They must have a great deal of love. I only hope I could have that much love to give if it was asked of me.
These little ones need as much love as can be mustered for them. To sit in judgment of God instead of acting as His instrument is a waste of time and effort, in my opinion.
No judgement. Only why.
