I think this thought process is something that only people who have never been wronged can afford. There comes a time in life where the punishment must fit the crime, even if its only to make an example of the criminal.
Life is hard enough, we should deter crimes at every possibility, people are rarely punished for every evil they commit.
I was mugged as a teenager, and my house was burned down as an adult because a drug dealer lived on the same street.
Does that count me as sufficiently wronged to not be dismissed for sharing the parent posters viewpoint?
See this is my point though, it shouldn't matter what has happened to you, if that matters, then this is 100% emotional and not based on reason or justice.
