The first is from a letter sent to the judge in Lewis Libby's trial. Lots of people wrote, saying he was a good man and shouldn't be punished.
The second is from a columnist writing about a woman who recently ran her car through a festival in DC causing the most pedestrian injuries DC has ever had in one event.
The third is from 2001 here in Manassas. While the mother and oldest of 13 children were away, the 21-month-old was left in the car by her father and died. Impartial report Catholic Article Kevin Kelly was called a "good Catholic" by many people who spoke at his trial. Apparently that was supposed to alleviate his negligence of his child.
It amazes me that people think that just because people are basically good means they shouldn't be punished when they do bad things. Do they believe that only thoroughly bad people do bad things? We have lots of evidence to the contrary. Is the ongoing good that a person does enough to balance something bad? Probably not. You don't build up good points that can be used against a bad event.
