Fire In the Hole and Nietzsche

"Whoever fights monsters should see to it that he does not in turn become a monster."
-Nietzsche

Last night, during the read-thru of Fire In the Hole, there was some discussion as to how Joshua Rowen becomes "corrupt," when he begins as a fighter against his corrupt father, Tommy Rowen. A lot was said in terms of what it means to be "corrupt" and why Tommy and Joshua see things the way they do. This quote seemed to sum it all up for me - I see it as a danger of falling to extremes. Tommy can't see the bigger picture, only his family matters. Joshua sees so much of the bigger picture that he neglects his family when he gets older.
