Not sure I would categorize Mercury's character (in the song) as either heroic or a fighter. He is certainly an active observer of his circumstances; however, he seems resigned to, if regretful of, his fate. His relationship with his mother is certainly different, at the very least in that he speaks to her (presumably) as a living person.

Also, Camus wouldn't likely be concerned with Beelzebub.

Mais, je pense que la comparaison, c'est valide.

Different, certainly, but comparable.

After all, "nothing really matters...anyone can see..."
