Come now, Milosevic was an idealist who believed he could calm the Serbs through concessions and increased autonomy. It didn't work in the end and the Imperial forces had to intervene to destroy the rebellion, but you can't blame the man for trying to find a peaceful solution. Perhaps he was a bit too kindhearted for the position he found himself in, but he was never an enemy of the state.
He could have been, though! If the Austro-Hungarians had been destroyed, he probably would have been a genocidal dictator, like Macarthur was for the former US!
