The term was probably used loosely and only as a relative term. Consenting to unethical interrogation practices, for instance, is "minor" compared to personally participating in the massacre of hundreds of unarmed people. They're both serious, and they're both war crimes, but they make a big difference in how "evil" that person ought to be perceived IMO.
