[交流] a conclusion from films

BAD ONE WILL DIE WHEN HE BECOME A GOOD PERSON

I have watched star wars （one to six）. And a feeling about the destiny of the leading role are very familiar in all films. At the beginning, maybe he is a good person or a bad person, no matter what, and become bad in the middle, and do a lot of serious things which would make every one want to kill him, and finally, he will become normal, and reget for all his behavior in the abnormal terms, but then the distence between he and his GOD is very close.

I believe all the audiences are have the feelings that do as a good one and do not be a evil person, but is there anyone have the idea: if he do not turn evil side to justice side, does the director let him die? or  not? why ?
