Accidents happen whether they're car accidents friendly fire drug overdoses. Accidents happen and they're tragic. It's like a bomb that goes off and pieces of shrapnel rip into the flesh of the family. It's the families that need the compassion because everywhere they walk every day someone reminds them of their loss.
If you desire to be pure have firm faith and slowly go on with your devotional practices without wasting your energy in useless scriptural discussions and arguments. Your little brain will otherwise be muddled.
