THe only way I can find some way to soothe myself when tragedy like this strikes is in the realization of the truth that we each pick the package of the life’s events we will agree to live here on earth, before incarnating down here. So there are things and challenges we must bear the burden of, for ex. sometimes we’ll see a cripple who suffers with a funny walk all their life. Well, no need to really feel sorry for them, as this was the best peckel their neshama needed and took upon themself in order to bring tikkun to the world and their charachter.
This kids’ time was up, as he had completed his tikkun. And he was also a special one as Hashem came and picked him, as a flower in a way, to take back to His Garden.
