Saddened by 2 incidents

Dear friends
Two things which i came across in the last one week,left me really sad,what is life really about?
One was a small girl of four who was rag picker ,father was also one,was raped. by someone when she was sleeping outside her house in the night.Her uterus and vagina were ruptured and she needs to undergo surgery to rectify a problem in her kidneys now.The father has no money and he has shifted 4 places now as the neighbours do not want to have them in their neighbourhood.How can anyone be so cruel.What joy can an animal(that man who did can only be called as such) get?
The second incident was the death of my daughter's friend last week.She had some physical problems but inspite of it she was attending school.She was good singer and was doing quite well in classes.But she passed away suddenly last week.Sometimes I fail to understand the stand taken by our creator.People would say it is purva janma karmas.But still it was sad that such young ones have been nipped in the bud.My late father always used to say that God's ways are amazing ,we come in one order but we leave in another.He was always worried when anyone of his younger brother or nephews or nieces fell sick.
I pray GOD to give this unknown girl and the my friends's parents strength at this hour.
