The poet has compared fire to the dark side of humanity i.e., hatredness and lust. According to the poet, lust is a greater evil. Desire or lust is the cause of war. Hatredness is also harmful. So the poem ‘Fire and Ice’ represents the two evils hatredness and lust which lead to the destruction of the world. According to the poet, fire stands for desire, greed and avarice. The more you try to satisfy them, the more they grow. There is no end to it. They spread rapidly like fire and ruin your whole life.
On the other hand, ‘ice’ according to the poet, stands for hatred, coldness and rigidity. One becomes insensitive and indifferent towards the feelings of others. One becomes selfish and sometimes cruel also. The poet says that both fire and ice are growing with such a rapid speed that the world would soon perish either way, in fire or in ice.
