In the poem "Fire and Ice" by Robert Frost, the impact of line 4 on the plot is that it illustrates the speaker's opinion on which force, fire or ice, is more destructive. The line "But if it had to perish twice, I think I know enough of hate" suggests that the speaker believes that ice, representing hatred and indifference, is stronger and more destructive than fire, representing desire and passion. This line helps to convey the overall theme of the poem, which explores the idea of how different human emotions can lead to the destruction of the world.
