It’s tempting to imagine that the Empire’s selection to shun armies of killer robots stems from the similar political and cultural reasoning for putting a general ban on killer robots within the first place. Maybe the substantial armies of killer robots have been nevertheless connected with all the former Separatist movement and had been consequently observed by most citizens with the Empire as only getting made use of by the “bad guy” Separatists.
There’s some help for this thought of a general anti-droid sentiment within the official Star Wars reference components. But that explanation seems partially undercut by the fact that the Empire still uses some military droids in particular supporting roles. Furthermore, quite a few citizens of your Empire nevertheless appear fine with non-combat droids performing many jobs, which raises the question of no matter whether the general anti-droid sentiment remains incredibly widespread by the time the original Star Wars trilogy requires location.
An alternative explanation in the Empire banning killer robots for the reason that of ethical or humanitarian motives appears laughable when taking into consideration the Empire’s policies of repression and intimidation. It is difficult to anticipate humanitarian consideration from an Empire that makes casual use in the Death Star – the key Star Wars weapon of mass destruction – to wipe out a whole planetary population depending on the justification that “fear will hold the local systems in line.”
Among the greatest explanations on the Empire’s disdain for killer robot armies was inadvertently presented by the Thrawn book trilogy inside the Star Wars Expanded Universe. The book series suggested that Emperor Palpatine, aka Darth Sidious, essentially exerted a form of thoughts handle more than all his Imperial troops. It is straightforward to envision how an Imperial military primarily based primarily upon weak-minded humans – susceptible to direct handle by only essentially the most powerful Force-users for instance Palpatine – may be more attractive than a robot army in that situation.
Regrettably, this Force-based explanation have to be viewed as null and void for the reason that the Expanded Universe books usually are not deemed an official a part of the canon Star Wars galaxy laid out inside the primary films.
