I don't think this is about religion. It could be about how someone hurts several people in the same way and the singer is the one observing it, "The same old story/But the names have all been changed", and this latest victim was strong enough to rise above and try to defend their self against the evildoer, "The fatal mistake you made/Was of all the hearts you'd slain/How you kept alive my bloody valentine ". Or all the above said but the singer is talking to themselves, "Aiming at the enemy
I only smash the mirror".
