Since the band has confirmed that this album is a story and this third of that story is told by the prison preist we know that is fact. the interpretation part is what the priest is thinking just before Kezia is executed.
I think that the priest is regretting taking part in a society that allows this kind of punishment. he is also doubting his religion, not that he doesnt believe in god, its that he doesnt believe in his organized version of religion what has him mindlessly saying prayers (like a parrot) from the bible (which is like a textbook full of formulas)
