I think a good example here is the death of Ben Kenobi in ANH. Luke grieves for him for maybe a minute, and then it’s back to “Great, kid. Don’t get cocky!”, screams of triumph, and a happy celebration for escaping. Does that disgrace Ben’s death? No, because eventually we find out he becomes a force ghost, so retroactively this type of behavior is more excusable right after his death.

We didn’t need the trio grieving Ben any more than that. We needed the thrills of the plot to keep going, even if it didn’t necessarily make sense.
