I read the sentence like:
In the interest of society they had better not have been born.
In the sentence above, I think we should put a comma after the word 'society' to divide adverb phrase and the main phrase. What do you think?

Punctuation conventions are unlike grammatical rules in that these conventions are taught at school, not learned as an infant. They are not a part of the grammar of the language per se. The primary goal of punctuation is clarity and avoidance of misunderstanding.
In the interest of sobriety, no alcoholic beverages are served.
No alcoholic beverages are served in the interest of sobriety.
The first sentence is clear enough: no alcoholic beverages are served and the reason is to foster sobriety. It would still be clear without a comma, making the comma discretionary:
In the interest of sobriety no alcoholic beverages are served.
The second sentence, however, could be understood to mean that alcoholic beverages do not foster sobriety. That is, the participial "served in the interest of society" could be taken to be the complement of "are".
For that reason the second sentence could benefit from a comma:
No alcoholic beverages are served, in the interest of sobriety.
The comma would be understood to indicate that the words "are served" belong together, this
{No alcoholic beverages are served} {in the interest of sobriety}
rather than this:
{No alcoholic beverages are} {served in the interest of sobriety}
So, the "takeway" is this: if you have a past-participle adjective like "born" or "served" in the role of predicate adjective, be aware that a prepositional phrase could be thought to modify that adjective and not your main predicate if the prepositional phrase follows the adjective. Move the phrase to the head of the sentence, or punctuate to avoid ambiguity.
