I think this is about Iron Maiden's lead singer, Bruce Dickinson. In 1992-93 when this song first came out, he'd just announced that he was leaving Iron Maiden to go start a solo career, saying that he was doing it because he wasn't happy anymore and that if he failed, so be it, which is basically what this song says. Also, his farewell show with Maiden ended with him being killed in an iron maiden torture device (the Slaughter of Bruce, get it?).
