As I understand it, in Dante's Inferno (which I admit I have not read in its entirety), the lowest level of Hell is reserved for those who maintain a "colorlessly neutral"—those who do not wish to get involved. In short, those who are unwilling to judge the behavior of others, especially when that behavior is reprehensible.

Rather than "judge not, lest ye be judged," it is far more courageous to judge, and be prepared to be judged for the judgments you make.
