Another question I asked led me to realise this seems yet to be addressed. We know that Ahsoka is not a Jedi de jure. However, is she considered to be a Jedi de facto?
At the point when she officially left the Jedi Order, she was vindicated of the crimes against the Jedi she was accused of, and was in fact offered a return into the Order. That means she is eligible to become a Jedi again if she so chooses, and the Jedi Council considers her worthy to be called a Jedi again.
However, she rejected the offer because she lost faith in the Order. She chose to "find her own way", which suggests she no longer fully agree with the Jedi ways as interpreted by the Jedi of the Late Republic.
Yet, one can also argue that the Jedi Order of the late Republic has grown arrogant and strayed from the true Jedi ways. In more ways than one, the Jedi of the late Republic can be said to be not how a true Jedi should be. This has been argued to death for years and can be considered to be largely true.
During the Imperial period, Ahsoka returned to embrace her Jedi heritage again at its purest roots, serving as a protector of the galaxy and its people against the Empire as best as she can. She has been known to actively involve herself in "Jedi business", protecting the interests of the future of the Jedi such as Force-sensitive children.
However, even though Ahsoka is actively attempting to prevent the complete extermination of the Jedi Order for good, we do not know her own philosophy of the Force, and how they align with the official Jedi philosophy. We know only that she is opposed to the dark side. This only ensures she is a pro-Jedi ex-Jedi, but this doesn't necessarily mean she is no different in her beliefs from a Jedi who never left the Order.
Considering the various points above (and others I may have missed), is Ahsoka a Jedi de facto?
