The motives for homicide and methods of killing were also compared with the corresponding motives and methods among murderers in Iceland and IndiThis study did not confirm a significant inverse or positive association between homicide and suicide in Jordan but confirmed the presence of a special unique motive (defense of honor) not present among murderers in Iceland and IndiThe study also confirmed that Jordanian murderers used more lethal methods of killing, such as firearms, compared with the methods of killing in Iceland and India
