Description . The HK protocol pacifist package was designed for use with the HK - series assassin droid to deactivate the droid ' s assassination routines and add pacification programming without the droid ' s knowledge . Designed to be downloaded onto the droid ' s behavior core , the module could be installed by even the least technologically - savvy being . The package also worked to suppress the droid ' s memories ; when asked to participate in combat or kill another being , the droid expressed shock and dismay at the concept and recalled none of its prior behavior as an assassin . Now acting as a translator and protocol unit , the droid became interested in teaching itself by means of educational activities — a desire instilled by the package ' s installation — including learning new languages and watching informative holovids . However , all of the functionality changes were not permanent : The package could be uninstalled , thereby returning an HK - series droid to its former self . The droid would maintain memory of the module ' s former presence and could maintain some understanding of the motivation for resolving conflicts peacefully , even void of the package ' s influence . History . The HK protocol pacifist package was created sometime between 4015 BBY and 3951 BBY . It was designed to restrict the assassination protocols of HK - series assassin droids and effectively turn an affected unit into a pacifistic protocol droid . During the Dark Wars — a series a conflicts between the remnants of the Sith Empire , the Sith Triumvirate , and fractured Galactic Republic and Jedi forces — in 3951 BBY , an exiled Jedi Knight , the Human female Meetra Surik , assisted Rodian merchant Geeda in the formation of trade routes between the planet Dantooine and Onderon ' s moon Dxun . As a result , Geeda came into possession of an HK protocol pacifist package , which she stocked in her storefront on the moon Nar Shaddaa . Surik eventually purchased the device at a discounted rate of 204 credits and later downloaded it into the behavior core of one of her companions , the assassin droid HK - 47 , as part of the Exile ' s attempts to upgrade the droid during her campaign . The installed module had an immediate impact on the droid ' s demeanor . Upon Surik ' s request to remain vigilant , HK - 47 vehemently opposed any violent activity and instead showed a desire to learn . HK - 47 ' s completely reversed personality drew concern from Surik and her other companions , including utility droid T3 - M4 , and Surik removed the HK protocol pacifist package . Restored to his original self , HK - 47 expressed disgust at the change forced upon him and requested that any further upgrades be run through a diagnostics bay before their installation . However , the droid begrudgingly admitted that the module had instilled some slight insight to the desire for peaceful resolutions . Behind the scenes . The HK protocol pacifist package appeared in the 2004 video game " " . It featured in a brief , optional conversation that rewarded experience to players and a permanent stat boost to HK - 47 .
