it's the person that wields it who intends to kill that is evil, but there's no denying that a wielder often defines a gun in the eyes of everyone else. examples: the AK47 is often associated with irregular troops in rebellions, terrorist groups, and Third World countries. the reason is that all of these favour the AK due to the fact it's reliability and simplicity make it perfect for those without military training and no knowledge of Firearms. the MP5 is the opposite: a "good guy's gun", because it is used by SWAT and special forces, people who save lives and catch criminals. a lot of this was thanks to the Iranian embassy Siege by the SAS, who used MP5s. the Desert Eagle is often reflected as a vulgar show of power, used by bad guys who want to show dominance and crave attention. it's appearance makes it desirable to the Gangster or thug who wants to be noticed. how many rappers have fantisized about shooting someone with a Desert Eagle? the same can be said about many Iconic guns; the M16, the MP40, the Colt 45. etc. people kill people, but the crowd that use a gun often give it a new definition.
