Well, that is pretty much how it feels from the inside, how it feels to Maedhros. It is he who believes, by then, that he inevitably dooms all around him.
But in fact I've written a story about Elrond in which he looks back, later, and disagrees with that assessment.
You say you "will have to re-evaluate your thoughts and feelings about Maedhros". I'd be interested in how exactly my piece made you re-evaluate your thoughts!
