I wasnt suggesting we read the Chad Gadya backwards. I am talking about the understanding of it. We need to have at the back of our mind the premise that G-d is always right and if that leads us to a question then we have Emuna that it is right even if we dont understand.
And it is not always about sechar veoinesh. Thats the point. What did the children do wrong in Mitzrayim or in Europe for that matter. But it is not a question because G-d Is right. Emuna and emuna and a bit more Emuna!
By the way the above answer I gave was not my own but I didnt quote because I cant remember the source. Trying to find it.
