To an anarchist, all rules imposed by society are statist, and criminal conduct is but a mere technicality important only to others.
An anarchist may be a moral person, without question. That has nothing to do with whether an enforceable law has been broken, although the statists who object to the criminal's conduct might consider it in determining the extent of the punishment.
I'm not an anarchist. And I have no idea whether or not you are a statist. My point was that all laws are not legitimate and thus the term "criminal" is a technicality. One can own a certain kind of gun nowadays and be considered a criminal by the statists. That hardly makes him immoral or criminal in the true sense.
