 Unlike Lost 's ensemble of characters who , according to the writers , each have good and bad intentions , the writers have said that Keamy is evil and knows it . Durand was contacted for the role after one of Lost 's show runners saw him in the 2007 film 3 : 10 to Yuma . Like other Lost actors , Durand was not informed of his character 's arc when he won the role . Throughout Durand 's nine @-@ episode stint as a guest star in the fourth season , little was revealed regarding Keamy 's life prior to his arrival on the island and Durand cited this as a reason why the audience " loved to hate " his villainous character . Critics praised the writers for breaking Lost tradition and creating a seemingly heartless character , while Durand 's performance and appearance were also reviewed positively . Keamy returned in the final season for a tenth and eleventh appearance .
