We look at the use of 'The Force' as a religious reality in Star Wars. How can people want 'good' when the force has dark and light?

For clarification, I saw 4, 5, and 6 in the cinema but possibly saw Star Wars or empire on tv first. 

Also, the change to the ep 4 title was for the 81 re-release on film.

Also, we originally thought of it as Star Wars, then sometimes would maybe talk about A new Hope being the title, but it was comon for us to say Star Wars.
