Now I've read that the split into these two factions of Islam happened early and centred on succession to the Prophet (may his name be praised etc) I also understand that the Shia's endured a right kicking under Saddams' Sunni centric regime. What I don't understand are the motors that continue to drive the Sunni/Shia conflict. What is at stake and what are the "goals"? I read that killing fellow muslims is a very bad thing for a good muslim to do - so unless the other faction don't count how is it justified by the clerics? Can't we all be nice to each other?
