Why are individuals made to suffer in this life? Why is there suffering in this world at all?
Wouldn't the world be a better place if there was no suffering?
The truth is, were it not for Yitzchok Avinu - there indeed would be no Yisurim / suffering in this life time!
However, he is not to be blamed. Or as the French say: au contraire mon ami! He is to be greatly thanked and lauded!
