"You can't have a light without a dark to stick it in." -Arlo Guthrie

Dylan Thomas was an amazing poet with a precise ear for the nuances of our language. In the poem "The Force that Through the Green Fuse Drives the Flower" he examines the dichotomies that make up life. Like the paradox inherent in the idea that pastoral beauty is made possible by the big bang that created the universe, or the possibility that human life on this planet was made possible by a meteor strike that wiped out most previously known forms of plant and animal life, Thomas is using language to pay homage to these conflicts.
In reading tarot cards, the card "death" is not indicative of a literal, physical death. It is rather a herald of great and transformative change. This is also true of the violence in the Thomas poem. Without the destructive freezing of winter, it would not be possible for the spring tulip to bloom. Birth is one of the most violent processes known to living beings, often far more violent than death, yet for all of its ferocity it is undeniably a creative force.
This is the spirit in which Thomas uses words like "force," "fuse," blasts," and "destroyer." Thomas is a poet who is deeply cognizant of the cyclical nature of life, and of the destruction inevitable within that cycle. His use of these forceful words leads the reader to consider the yin/yang conflicts of birth and death, and the way that looking forward to the joys of each new day in the best, most carefree times of our lives is still effectively rushing ourselves headlong toward the end of life.
