Every time  I watch the movie and it comes to this part it makes me cry , but not only because of Padme's death,  but also because of Obi-Won, Yoda, Anakin, Qui-Gon Jinn , Han Solo ( whom btw I got spoilers due to the fact I haven't watched The force awakens  )  but R.I.P all of them . This song is so strong it gets me all the time . T-T

This is the way I see their deaths

Padme : killed by Darth Sidious to give Anakin or aka Darth Vader life , as far as I'm concerned she wanted to live , she was fighting for her life/ children

Anakin: ( metaphor ) killed his humanity and all that made him who he was the minute he was seduced to the dark side.
And even tho he at the end of Return of the Jedi came back to being Anakin once again , just to see him die again , but this time he died for good, ((his body and soul )) as Anakin this time .
(If that makes sense )

As for the rest they all died protecting those they loved.

Well for Han idk and don't tell me >.< I want to see for myself
