But the movies don’t imply she’s got a struggle about the dark, it’s only her origins and her use of lightning that we see. There’s nothing onscreen about her genuinely having a tendency towards evil deeds, she only ever acts to help her friends. She has dark power, and sometimes takes the easy (powerful) path, but only ever still for good. And she sees herself on the throne, but that’s not a temptation for her, because she says she doesn’t want it, and at no point do we think she intends to be some dark ruler from it. She has a grievance against Palpatine specifically (he killed her parents indirectly) but again that’s not something that’s going to bubble over into full evil, like Anakin slaughtering tuskens.

It’s enough that she’s facing Palpatine because he’s a huge threat to the galaxy and her friends, and confused and perhaps emotionally compromised by visions of the throne. Her challenge there is showing that she’s not a worthless scavenger girl - she’s a Jedi.

And I agree that that’s a less powerful conclusion than her storyline deserved, certainly less powerful than the temptation of Luke. But even with modified dialogue I don’t think we have enough onscreen performance to imply that there’s a genuine temptation to evil here.
