Syndicate was a robber. He sometimes acted as a thief, sometimes as a pirate, sometimes as a smuggler, and sometimes as a helper who did something unsuitable for important men who didn't want to reveal their identities.
He didn't care what he was doing on earth. As long as he could make money, whatever he was asked to do was acceptable.
In private, he called himself a "Cost-free Gentleman." The former implied his identity, and the latter flaunted his style of doing things.
