but killing him off and breaking up Indy and Marion after Crystal Skull bringing them together seemed a bit like Star Wars breaking up Han Solo and Leia. Harrison just can't catch a break, I guess....
Having Deckard, Han, and Indy make comebacks in the recent past, all having lost their loves makes me think this is something Harrison wanted. Like his notes for the script? Maybe he felt that makes it easier for him to emote, or find an anchor for the character. Maybe, maybe not? I just try to give the benefit of the doubt, rather than it be "lazy writing"
