A person who does not take the message of Hashem from such a tragedy, and whose life moves on as usual afterward, is not responding to the tragedy. How can a person see so many who did pass away and not change for the better? How is that possible?
The Rambam goes on and says that if the Rabbis are not going to call for Teshuvah (repent) after such tragedies, people are not going to repent. And if people are not going to repent, says the Rambam, then even more tragedies can happen. These are the words of the Rambam. I quoted them to you literally, word by word. The words of the Rambam, right at the beginning of the first chapter.
He says our job when such situations happen is to scream at Hashem and pray. Life cannot move on as usual. Life can never be the same. Change for the better. And every person knows himself, and I’m talking to myself. Change for the better has to happen. If Hashem gave us such a drastic tragedy that we just witnessed, that means the outcome, the response, the result after such a tragedy—the change—has to be drastic too. And if Hashem chose us to live through such a situation, that means we are capable and we are bigger than any tragedy that comes our way.
