How are Akiba and Elie similar? How are they different? according to chapter 5, pg 45 - 77

Akiba and Elie had both lost their faith in God during this period. Akiba, however, asked his fellow Jews to say the kaddish for him after his death..... revealing the fact that his faith was still there if not as strong as it once was. Elie, on the other hand, was unable to find his faith during this period.
