I love this song so much, and I could just imagine myself with a gun being swarmed by thugs. I'd be surrounded and I'd be trying my best to stay alive. Then I get a minigun and this music starts playing and I kill everything... ah, fantasies, they're wonderful things.
More seriously is that in my groups I'm seen as the protector, because I'm significantly larger than most people I meet. As a result I usually develop a reputation as the guy who will save your kitten from a tree one moment, and then if you hurt one of my friends I'll snap your spine and crack your femur in half (not that severe, I hate hurting people, and the most I usually have to do is restrain them).
I think this song has an element as if someone is a protector or mentor, someone who would not let harm come to those they care about, and I think that is me.
