Some verses describe the most wicked on this earth. Other verses happen to describe someone who can take the bad along with the good - and maybe it's the artist themself, but I believe the "character" in the song isn't a wicked nefarious person. Then again. "No one will know how evil I really am." - and "only god can judge" so when the "divine judge" can see into your heart - I have no fears and no doubts just how evil I really am. My "behavior" that worries me? It's the intrusive thoughts, from people acting out in unbecoming behavior; almost like the impulse to Tourette's syndrome, but in this particular disorder - it's an impulse to mimic whatever they do. I couldn't even speculate, is it a love for impressions as a child [no] or is it perhaps the typical inherent social pattern to subconsciously copy the body language or tone of the person who is engaged in conversation with you [perhaps] - and if either of us dig further you're getting into speculation and a comfy armchair for a wannabe pseudo-psychologist.
Remember when I first listened to this song, and the end always struck a cord with me because I was in a bad place but now I can indeed stand in a place of comfort confidence and dignity (been at least ten years)
