I feel two things
It's interesting, and not very many songs do this. I see this as two emotions clashing. You can argue that the song is happy, but not a "Awesome I'm getting married!" or "I've done it!" to be generic, just one of those bits that play when the camera zooms out, showing the few remaining soldiers standing up as the beast lay slain, and the number of moving soldiers gets drastically beaten by the number who will never move again. They've won, but the cost was great.
While this is happening, I see it as the opposite. The beast beat the army, and the last soldier alive just has enough time to receive a quick flash of his wife and kids before he too, joins his comrades.
Not really a review, more of what I felt, but you can take this as you choose and in a way, that is a review, showing you what your music provokes.
