I agree its Itachi but he wasn't forced to kill his clan, he was asked and he agreed, and he admitted himself that was the only way to stop them so none of that sounds like he was forced. His younger brother later learned the truth and loves him and now wants to live as Itachi did as a true shinobi one who " endures ".Title says it all honestly I think Itachi has because he was forced to kill his clan in order to protect the village. He also had to die being hated by his younger brother and the rest of the leaf.
