There is a Gemara (Shabbos 32a) which says:
??? ??? ??? ?????? ?? ???? ????? ???? (????) ???? ?? ????? ???? ??? ?????? ???? ?? ??? ?????? ???? ???? ??? ???????? ???? ?? ??? ???? ????? ?? ??? ????
There is a lot to think about from a philosophical standpoint with regard to this Gemara, but I think that the main thing it teaches us is that whenever a tragedy occurs it is not for us to point blame at one party and vindicate the other. Everyone involved is at fault, because if they were not, Hashem would have directed the circumstances so that anyone who was not at fault would not have been involved.
