No exacly. It depends on the point of view you have and what is bad, criminal for you.
It also depends on their goal, the enemy or the situation.
For example, if someone kills the Vittorio Amuso(Aka Michael Douglas, it´s not official but I guess he deserves to have this nickname you know why)´s son, then Amuso order the killing of his son´s killer, then It´s justice and not a criminal act. Many people think you are just a criminal because you killed your father´s killer, but those people think like this until it´s their turn to lose their parents, children or whatever by the gun, knife, poison or whatever it is of a killer.
