It's important to show sometimes Picard is wrong and the institutions are wrong. And how he reacts to that.

One of my favorites is Star Trek TNG s04e22 "Half a Life". It's excellent scifi that doesn't glorify aging and death and even points out that death is bad despite it being tradition in society. It highlights that death is the worst possible outcome. Worse than nearly all potential difficulties or suffering while living. And it's one of the few episodes where Lwaxana Troi is a genuinely good person. Better even, ethically and morally, than the star fleet standard. Better than Picard. It's just a shame the episode retreats from it's message at the end and does not embrace the true morality Lwaxana explains.
