I'm not sure without more context. It could be a final wish like seeing a loved one, achieving a long - held dream, or perhaps making amends for something he had done wrong.
Maybe it was forgiveness. In many true stories, when someone has made mistakes or had a difficult past, the last thing they truly long for is to be forgiven by those they've wronged.
I don't really know. It could be a mix of real and made-up stuff. Sometimes stories are inspired by real life but changed a lot to make them more interesting.
It was probably because it went against his principles. For example, if he was an honest person in the true story, the last thing he would want is to lie or cheat.
Perhaps it was giving up on his dreams. Think about it. If a person has been striving for a dream based on a true story, like becoming a famous artist or athlete. All the hard work, the sacrifices made along the way. So, giving up on that long - cherished dream would surely be the last thing he desired.
Well, it might be because it was the key to his emotional healing. For instance, if the last thing he wanted was to reconnect with a lost loved one, it could mean that this connection would fill a void in his heart that had been causing him pain for a long time.
I'm not sure specifically which 'the last thing he wanted' true story you are referring to. There could be many stories with this title or a similar concept. It might be about a person's final, most dreaded or unexpected experience.
