Hmmm
Well, as a poem, I would accept the text as it now stands. For a native speaker, it is a perfectly normal poetic text, and adding verbal redundancy could be considered to be damaging the poetic quality of the the poem.
At any rate, here is my understanding of what the writer is saying, for the purpose of translation / bridging:
---
I think that I am a good example of the extreme opposite qualities that humans can possess.
I feel extremely deep love, but I can also be unyielding
(and unforgiving).
I can be
(as pure as) a saint, or
(as irreligious and irreverent as) a someone who doesn't believe in religion at all
(or who believes in a different religion, or in a different way).
I possess both masculine and feminine qualities in their entirety.
I can contain what seem to be absolutely contradictory extremes within myself, just as other humans do.

Of course, as poems are more Objective than our usual Subjective way of communicating our ideas, they are more open to interpretation than usual communicative expressions. My above interpretation therefore also contains my interpolations about this poem's meaning: other readers might have added different interpolations...
