Ahsoka Tano left the Jedi Order because she was falsely accused and framed for bombing the Jedi Temple, which led to her arrest and expulsion by the Jedi Council. Although she was eventually exonerated, the lack of trust and support from the Jedi Order during her trial left her disillusioned. The Jedi Council offered her the chance to rejoin, but she chose to leave permanently, feeling betrayed by the institution she once believed in and uncertain if she could trust herself or the Order anymore. Her departure was also influenced by witnessing the Jedi Order's flaws, politics, and dogmatic rigidity during the Clone Wars, which clashed with her values and personal integrity.
