Can’t tell if you’re joking about the Boromir part. But if you’re not, you’re dead wrong. He only ever did what he thought was in the best interests of his people. For his entire life, he has grown up facing an incredible evil on his doorstep, watched his countrymen die, and as the heir to the Steward it was all on his shoulders. In the end, he realized he was wrong and he gave his life trying to make up for it.
