Owen was a kind and caring individual, but he was also gruff and strict, which often created tension between him and his step-nephew, Luke Skywalker, and which often forced his wife, Beru Whitesun to mediate between the two, Owen bore great disdain towards the Jedi Order, as he believed that Obi-Wan Kenobi had warped his step-brother, Anakin Skywalker's mind into leaving Shmi alone on Tatooine, an act he considered to be unimaginable. Owen felt that Obi-Wan was personally responsible for the deaths of Shmi and Anakin and, that the Jedi Master's actions had ripped his family apart.
When Obi-Wan left Luke under Owen's reluctant protection as an infant, he told the Jedi Master to stay away from them, fearing that Obi-Wan would create similar consequences with his step-nephew in the future, to keep Luke from following in Anakin's footsteps, Owen lied to the latter about his Jedi heritage, claiming that his father was simply a navigator on a spice freighter, when Luke desired to leave Tatooine, Owen found it difficult to ignore his gruff, protective nature, which had become habitual over the years and, tried to come up with excuses to keep Luke from leaving Tatooine. Owen failed to realize that he was running out of excuses and, that it was inevitable that Luke discover the truth of his Jedi heritage.
