 Booth once told Sweets that while he has killed (because he was following orders), he has never murdered.It is stated that Booth will not pull the trigger unless he is absolutely certain of the identity and guilt of the "target" he is about to kill and that it is sanctioned by a higher authority and not on his own volition.Booth views the law in a similarly subjective way and believes that committing a crime is never justifiable regardless of the circumstances.
