[Strangler Lewis]

If you rob an old lady or abuse a position of trust to embezzle money or molest a kid, or if you associate with a gang that prompts you to commit a robbery, you're going to get a higher sentence than someone else who commits similar crimes. There is nothing wrong with identifying behavior or beliefs that carry with them a higher potential for believing that criminal activity is justifiable or can be gotten away with and then punishing the yielding to those temptations more severely as a means to deter others.
