Star Wars Storytelling

In 19 71, the irish republican army has been reborn as a well equipped and zealously dedicated per military organization. They have one goal, to make britoin's occupation of northern ireland so painful that it would be forced to loosen its grip on the region. But what happens when the rebel alliance bombs a crowded market place full of innocent people? What if luke skywalker used his light sabre to butcher an unarmed contractor whose only crime was installing light fixtures on the death star? We'd feel a little bit differently about the righteousness of their cause, wouldn't we? How would we reconcile our sympathy with their struggle when they wage war is so morally bankrupt?
