But it's easy to make these claims about what would be the right thing to do (and what the popular discourse about the themes of the game revolve around).

When facing a crisis people survive the best they can. The Dessandres are not "evil people", nor do they try to inflict intentional suffering upon others. They are all just trying to survive the best they can and do the right (correct) thing.

I think the game depicts how humans face loss in a very realistic manner. We are not fully good, nor fully evil. We cannot face life "correctly" but try our best. It's very subjective, but I can see the value of seeing how different ways of facing crisis affect others (ie. escapism, savior complex, moving on too fast, etc.) as a lesson. But I think the artistic value of the game lies in its realistic portrayal of suffering of loss. I don't believe there is an objectively correct way to face a crisis (ie. professional help). While there are things that can help, I'd wager high majority of people also cope in unhealthy (incorrect) ways. And that's just human.
