Misconception: Ahsoka is partially faulted for Anakin falling to the dark side.
SEND AN ASSUMPTION/MISCONCEPTION ABOUT AHSOKA
ahsoka was an unknowing step down on an already very unsteady ladder.
no doubt she weakened anakin's resolve to stay in the order, but he was already inching toward that path to the dark side with or without her. did it perhaps speed up the process? 100%. in much the same fashion as anakin's nightmares concerning padmΓ©'s death as padmΓ© came closer and closer to her due date.
but would we really say padmΓ© is at fault for pushing anakin toward the dark side? no, i don't believe so. by definition, ahsoka's departure and the nightmares about padmΓ©, plus her increasingly nervous behaviour around him as he spiraled, were catalysts to anakin's eventual fall, but not causes. i say this especially because ahsoka and padmΓ© loved anakin very much and cared for his well being deeply, but they had a whirlpool of their own terrible circumstances to work through, too.
conversely, i think padmΓ©'s and ahsoka's presence in anakin's life may have made it easier to cling to the light while they were around him. as soon as they began to feel distant, the fear rushed in.
in particular though, ahsoka's departure from the order was never because of anakin. it was in spite of him. even though he may have done all he could to ensure her exoneration, the rest of the jedi council thoroughly mucked up the process. their mistakes were never his fault, nor would ahsoka ever dream of insinuating such a thing. but anakin may also have feared he didn't do enough to renew her faith in the jedi, yet he was the only one who did enough. that's something i believe ahsoka tried to tell him in her own way before she left. once she was gone, though, every dangerous worry in anakin's head could run free.
so, to me, while she was a contribution, she isn't a cause. she isn't to blame. anakin's choices were always his own, even under the heavy and damning influence of palpatine.
( while really valid comparisons can be made to a steep mental health journey loaded with negative outside stimuli, anakin had options. he just had immense difficulty seeing them for what they were due to extreme stress. difficulty like any of us would have. not only was his destiny seemingly written for him by uncaring hands before he ever had any kind of say, but he was suffering under all that pressure, tricked into believing turning to the darkness was his only choice. but it wasn't. vader was a victim just as much as he was a villain. just as much as he was a hero. there were ways out, he just couldn't see them at the time. and if anyone reading this feels any kind of similar pressure or similar growing fear that you'll never make it out of the dark tunnel you're trapped in, you can be free. there is a way out to freedom for you and i believe you will find it. from someone who's been in that dark tunnel, strength shows up at strange times. you do have it in you to save yourself and become your own hero. i believe it, without a shadow of a doubt. you can do this. )
