Stormtroopers are good shots
At times their aim may seem suspect, but there are countless examples to suggest the Stormtroopers may be the best fighters in the universe. Take, for example, the fact that they slaughtered the Jedi when Order 66 was executed, and their repeated ability to defeat the rebels. And don’t forget the time Stormtroopers kill Luke’s Aunt Beru and Uncle Owen and a group of Jawas while framing the Sand People: Obi-Wan explains to Luke that it couldn’t have been Sand People who attacked because “only Imperial stormtroopers are so precise.”
Luke could have joined the empire
It’s a quick moment in “A New Hope,” but Luke Skywalker mentions to Uncle Owen that he might “transfer my application to the Academy.” At that time, he could have only meant the Imperial Academy, which is why some critics and fans argue that Luke could have joined the Dark Side, despite his good intentions. However, it’s entirely plausible that he would have defected just as many other rebels did.
