No. All that is needed for success as a criminal is the absence of intelligence on the part of the law.
Of the vast number of successful criminals in this world, few are genius super crooks, who lay subtle, twenty year long plans to confound the genius police forces (which rarely exist).
The quote above seems appropriate for some Agatha Christie novel, where the detectives are so clever, that only the master crooks can almost beat them. Crime in reality is more a competition of lower stupidity than greater genius.


Their score is 500 to 0? In which book series? You make the mistake of measuring their success by the body count of a gang of 15 people! You ignore the vast suffering, the major wars and the sheer chaos they have spread to the common man.
Maybe that is RJ's greatest flaw. That he failed to show us how Graendal's actions affected the common Domani, how Semirhage's actions have wrought unspeakable suffering in a huge continent, how Sammael, Asmodean and Rhavin sent thousands to deaths. Because we can only appreciate these in a cerebral fashion, too many people tend to write off the evil of these characters.

Imagine writing off Hitler as one of humanities greatest evils because he never won a duel and in the end shot himself. Imagine writing off all the deaths of the millions of Jews because Hitler was a moron whose idiotic policies saw the most brilliant minds rush to America to help in the construction of an atom bomb. Imagine writing off the instigator of the most destructive war human kind has seen because he was paranoid and a megalomaniac who failed to use his best generals out of fear.

Because that's what you're doing here.
