Answer:
The poet uses if to indicate that whatever he is referring to does not have to perish twice.
Explanation:
By adding if, it signifies this is not actually happening, and it is more of a "what if?" statement. If the sentence was left without it, it would imply that is has to perish twice.
"But it had to perish twice."
See the difference?
