Another Question for Poets

For the question project (five questions to ask different poets and perhaps post here), I thought to ask,

"What is the poet's duty?"

But this question seems too bound, too mired in some sort of filial piety or some such.

My wife, however, came up with this:

"What is the poet's responsibility?"

This one hits much closer to the quick, easily understood but provocative question I like. The only issue to decide now is whether to use "a poet's responsibility" or "the poet's responsibility."
