At first I thought love as destruction due to the simple fact of speaking of death, guns, rain of lead and a general violent picture. But I think it is love as devotion. It is not the bullets and the destruction that is the point of it. The point, as I see it, is how far he is willing to go for her. What he would endure, do for and together with her (which arguably can be destructive in nature, perhaps). And even if their journey should take them to an extreme end in a rain of lead, he would still end his days looking in her eyes and be with her, be there for her.
It almost feels like the panic having no escape. The desperation of seeing the inevitable coming for you and you have no way of escaping it.
