SPOILER - What were the motives?
I watched both the first and the last episodes but mist some in the middle. So while I'm aware of the main plot and how it ended, I have no idea WHY Bruno went on the killing spree.
Having seen the first episodes, I know of course what happened in school when the four pupils were burned to death but what was their connection to Bruno and why did he kill such a huge number of people. The teacher, Renzo, Laura, Benitez - sure, I understand that he thought them responsible but all those deaths? And most of all, once again, what was his connection and feelings?
