Answer: Robert Frost; Fire and Ice.
Step-by-step explanation:
The poet is Robert Frost and the poem is "Fire and Ice". The poem is about the demise which hatred and obsession will bring. The poem is about the apocalypse, and the poet writes about how the world will end. He said some people are of the opinion that the world will be destroyed by fire, and others argue that the world will be frozen.
But if it had to perish twice. I think I know enough of hate expresses a comparison between the fire and ice or an obsession or hatred. Even though they're re different, they have the same outcome which is destruction.
