I could not resist purchasing and reading a book that was attempting to make the point that there it is something good about being bad.

With only 32 pages (plus the notes) it is a pamphlet more than an essay.

The first important point of the author is the split of the behavior as private citizen from the one as a public officer.
The importance of being good in our private live is recognized and then the author moves on explaining why being bad as a public officer sometimes is not only acceptable but badly needed.

Then the book shows several examples of “bad” behaviors from public officers that led to a lesser damage and examples of “good” behavior that led to major public damage.
If the state, and as a consequence the people with public roles, is unwilling to use some degree of violence there it is no point at all in having a state because the individuals that disagree with the government decisions can’t be forced into accepting them.

Bad guys, without quotes, are born every day: a state that can be “bad” is needed.
