Kierkegaard writes, "Anxiety about sin is sin." Wow, I know exactly what that means... (?)

I am not a huge fan of the book because it is very dense, laden with technical and sometimes Hegelian language. I am likely to be misinterpreting key points in Kierkegaard's argument but I shall press on anyway and try my best to formulate my exact concern. At the outset, Kierkegaard lays out the groundwork for the phenomenological sense of anxiety, which, in itself, is evidence of free will. He uses the story of Adam and Eve as his launching point, and posits that the feeling of anxiety comes about right before a decision. Kierkegaard talks about different kinds of anxiety. For instance, there is anxiety about "fate," which affects a forward thinking "genius" who is fixated on the consequences of his actions. Anxiety about sin-- he seems to argue-- causes more doctrinaire, religious types to ruminate on things they have done wrong (i.e. commandments we fail to obey, etc.) These people are so paralyzed by the fear of their past missteps, specifically by the prospect that what they did was irredeemable, to the point that they end up paralyzed. They never look forward to future, redemptive acts because they are too convicted by their own impiety. Kierkegaard, during the exposition of this sort of anxiety, writes that anxiety about sin is sin. 

How is that? Does the underlying anxiety that comes with flagellating oneself about the past to a debilitating degree force the kind of paralysis that is within itself sin? In other words, is Kierkegaard, like Sartre, posing a radical freedom that requires us to move forward and choose fearlessly? Is the failure to do that a sin, even if the failure is a paradoxical result of the fear of sin? Perhaps, that's the role of faith in Kierkegaard's framework too. The belief that a sincerely honest attempt to choose "rightly" is all that's required, and we must have faith in our capacity to do it. If we fall short one time, Kierkegaard might say, our faith becomes all the more important the next time.

Sin being an ancient term that means ‘to miss the mark’, I’d posit that worrying about the spectre of ones past and future failures or misdeeds is a form of pre-emptive failure against the self’s ability to live with true purpose, and is thusly, itself, missing the mark.
