Yep, that's pretty much it. "Everybody was upset. I was struggling with the problem that I had this sort of climactic scene that had no climax about two-thirds of the way through the film. I had another problem in the fact that there was no real threat in the Death Star. The villains were like tenpins; you get into a gunfight with them and they just get knocked over. As I originally wrote it, Ben Kenobi and Vader had a sword fight and Ben hits a door and the door slams closed and they all run away and Vader is left standing there with egg oil on his face. This was dumb; they run into the Death Star and they sort of take over everything and they run back. It totally diminished any impact the Death Star had." It was like the old Bob Steele westerns where they all had about fifty shots in their six-shooters. "Right, but those kind of things dissipate without having a lot of real cruel torture scenes and real unpleasant scenes with the bad guys in order to create them as being bad or make them a threat. I was walking that thin line between making something that I thought was vaguely a nonviolent kind of movie but at the same time I was having all the fun of people getting shot. And I was very careful that most of the people that are shot in the film were the monsters or those storm-troopers in armored suits. Anyway, I was rewriting, I was struggling with that plot problem when my wife suggested that I kill off Ben, which she thought was a pretty outrageous idea, and I said, 'Well, that is an interesting idea, and I had been thinking about it.' Her first idea was to have Threepio get shot, and I said impossible because I wanted to start and end the film with the robots, I wanted the film to really be about the robots and have the theme be framework for the rest of the movie. But then the more I thought about Ben getting killed the more I liked the idea because, one, it made the threat of Vader greater and that tied in with The Force and the fact that he could use the dark side. Both Alec Guinness and I came up with the thing of having Ben go on afterward as part of The Force. There was a thematic idea that was even stronger about The Force in the earliest scripts. It was really about The Force, a Castaneda Tales of Power thing." --George Lucas, Rolling Stone interview; 1977. So blame George and Marcia.
