@90shal if i remember correctly, i think he wants find and kill the sith lord and goes dark to help the son do it. pretty sure there’s a dialog about it from the son to anakin.
The original Star Wars myth wasn’t really about “rebellion.”
It’s about the restoration of righteous order.
It’s the wisdom of the old Arthurian tales set in space, not Bolshevik revolutions in a galaxy far, far away.
Rebellion is not inherently good.
