Repetition can make a good impact, but it's beyond excessive in this instance. Contrast with this poem:

    Non est salvatori salvator,
    neque defensori dominus,
    nec pater nec mater,
    nihil supernum.

Translated:

    No rescuer hath the rescuer.
    No Lord hath the champion,
    no mother and no father,
    only nothingness above.

- Eliezer Yudkowsky

I find this one profound, and it's given me a lot to think about over the years - in situations ranging from asking what our place in the universe is, to doing the "right thing" (and deciding what "the right thing" even means to yourself), or standing at the helm of some team or project, knowing that judgement call is yours alone and there's no authority or higher power coming to swoop in and give you the answer or authoritatively judge your decision can be simultaneously liberating and terrifying. The use of repetition works incredibly well in my opinion and it still gives me chills to read it.
