What am i? . . .

I am the dark side of your conscience
I am your sin in your soul.
I am the aching in your heart,
I am the devil that creates fire.
I am the problem that creates another
I am a life that can lead to a death,
I am a problem you cannot forget
I am a thing that leads to a mess.
I do not give in to your plea's
Yet I'm something you cannot see...
I am Curiosity!
