This will be short:
Sin is, by nature, a mutation/error/dyfunction of good/true/works well, etc. Therefore, sin doesn't make sense. It is not congruent with reality, and probably is not congruent with itself.
Oftentimes I have been distressed by questions, thinking that goes in circles, fixation on one idea without being able to escape. I have always attempted to wade through these, draw the dots between the data, figure out why I feel these ways, etc. However, sin and error being illogical, cannot be internally defeated and must be discarded. Realize that you have NOT found the truth, and simply abandon your current train of thought.
