The Father, Anakin, and the Holy Spirit
Yeah, remember how we said we’d avoid the topic of religion? We lied. But this is the final time, we swear. It’s common knowledge that some people view Anakin Skywalker’s journey to be somewhat in line with the historical Jesus of Nazareth. After all, they’re both “The Chosen One,” though it’s fair to say that Ani wasn’t exactly sinless.
However, in Return of the Jedi, Darth Vader makes the ultimate sacrifice by giving his life to save his son, Luke Skywalker. So, in a way, one might say that Darth Vader had to sacrifice himself to save another person’s soul.
