Why didn't Yoda fall to the Dark Side？

A character that exudes strength and wisdom rises out of the shadows in the enormous and complex fabric of the Star Wars story. Yoda endured great hardships and temptations over his legendary life, but he never wavered in his dedication to the light side of the Force. There was a remarkable moment when, like all Sith Lords, Yoda's aged eyes flickered with a frightening yellow tint, leaving one wondering if he might turn evil.

Canon Perspective:

In the history of Star Wars, Yoda is portrayed as a shining example of Jedi virtue, with unwavering convictions and an unmatched bond with the Force. A Jedi star, he was a steadfast defender of the Jedi Code, his soul the one nearest to the Force's ethereal core since the death of the great Qui-Gon Jinn. Even though hints of temptation might have already touched his awareness, Yoda stayed firm, his determination unflinching and his dedication to the light side unyielding. He protected himself from the seductive grip of the dark side by maintaining this unflinching loyalty, which made sure he would never waver.

Legends Perspective:

The enormous tapestry of Star Wars Legends tells an incredible story that reveals the depths of Yoda's remarkable resistance to the dark side. When the galaxy was in a state of anarchy during the Clone Wars, Yoda and Count Dooku happened to cross paths unexpectedly. They conversed in a way that belied the hostility that raged between them, a moment that defied the expectations of their intense conflict.

Count Dooku, a crafty and evil Sith Lord, attempted to trap Yoda in the sacred corridors of their encounter by luring him in with the seductive charms of the dark side. Through a network of promises, he offered control, power, and a perverted feeling of independence. The sensual mutterings that escaped Dooku's lips, however, failed to sway the unflappable Yoda, who was protected by his unflinching determination.

However, the full extent of his resistance was not revealed until Yoda made a revelation. He gave himself over to the dark side's insidious grasp in a stunning act of daring, allowing it to surge through his being. The lines between Yoda and the dark side were briefly blurred, and their spirits merged in a dance of power and malevolence.

But as quickly as the dark side took him, Yoda came out of it unharmed, his true self returning with a dazzling clarity. The dark threads that had attempted to trap him were thrown aside as the unwavering Jedi Master regained control over his spirit. As he observed this remarkable display of self-control, Count Dooku shuddered in amazement and fear. He understood that Yoda would surpass even the might of his own evil master, Darth Sidious if he were to be engulfed by the darkness and become an unstoppable force of destruction.

Conclusion:

Yoda's steadfast self-control and persistent devotion to the light side of the Force are an ethereal tribute to his victory over the dark side's alluring charms throughout the history of Star Wars. According to canon, his unwavering faith in the Jedi Code protected him from temptation and guaranteed that he would always be impervious to the Sith's siren's call. According to the Legends story, Yoda's incredible self-control was revealed when he managed to momentarily enter the embrace of the dark side without giving in to its seductive talons. Yoda's status as a shining example of Jedi integrity and a guardian against the approaching darkness was cemented by this breathtaking performance.
