There are so many different people that you could discuss here.
As mentioned below:
-Gandhi
-Nelson Mandela
-Martin Luther King
Also:
-Mother Teresa (fighting for justice)
-Brown vs. Board case of 1954 (fight for freedom)
-Kitty Genovese (bystander effect)
-Turia Pitt (fighting for life)
-Everyday police officers/firemen/paramedics/soldiers
-Holocaust stories (people risking their lives to save others)
-Oskar Schindler
-Elie Wiesel
-Heath Ledger (battle with depression/drugs)
-Kurt Cobain (depression/drugs)
It doesn't have to be anyone super-famous, as long as you tie in the stories appropriately. Don't forget to try and tie in your examples with Najaf's story if you can, eg: Just like Mother Teresa in Calcutta, Najaf wanted to help in the detention centre (or something like that)
The list is virtually endless if you really think about it, hope that helped
