 During the casting process , Keamy was described as a military type in his late @-@ twenties who does not question orders . Chris Carabott of IGN wrote that " in a show that features characters fraught with uncertainty , Keamy is the polar opposite and his Marine mentality definitely sets him apart . His team has a physical advantage and with the help of Mr. Widmore , they have a tactical advantage as well . Keamy is like a <unk> being thrown into a cage full of kittens ( except for [ Iraqi military <unk> ] Sayid ) " . Jay <unk> of The Huffington Post , stated that " Keamy is Crazy ! … out of all the bad guys on the Island — past , present , and future — Keamy has to be one of the most dangerous ones . Not because of how big he is , or the weaponry , but his willingness to kill at the drop of a hat . That doesn 't <unk> well for our <unk> [ protagonists ] . " Co @-@ show runner / executive producer / writer Carlton <unk> has stated that he and the other writers create " complex " characters because they " are interested in exploring how good and evil can be embodied in the same characters and [ the writers are also intrigued ] the struggles we all have [ , ] to overcome the dark parts of our souls " ; however , he later clarified that there is an exception : " Keamy 's bad , he knows he 's bad , but he 's ... a guy that does the job . " Damon Lindelof stated that " the great thing about Keamy is that he is like a ... merciless survivor . [ There ] ' s this great moment [ in the season finale ] where he just sort of <unk> @-@ sacks [ a grenade thrown at him ] over to where [ his ally ] Omar is standing . Omar is certainly an acceptable casualty as far as Keamy is concerned . " According to a <unk> in the Lost : The Complete Fourth Season – The <unk> Experience DVD set , Keamy likes " heavy weaponry " and " physical fitness " and dislikes " negotiations " and " doctors " .
