Ames spied for money; Gordievsky was driven by ideological conviction. Ames’s victims were rooted out by the KGB and, in most cases, killed; the people Gordievsky exposed, such as Bettaney and Treholt, were watched, intercepted, tried by due process, imprisoned, and eventually released back into society. Gordievsky risked his life for a cause; Ames wanted a bigger car.
