While I also wanted him to meet the past party members... it may be for the best they did not meet.
Sure, they feel bad because they did not notice that his bad actions was not because he was taking advantage of being a hero, but because he had already decided to give up his life anyway so he was just enjoying what he thought was the last days of being alive.
But that also added a new perspective to them about others, one that could help them with their new careers, and that could be ruined if they found out he did not really sacrifice himself. Would they believe he just happened to be saved, or would they think it was all planned out? With who was the one to end up saving him, the very one he was supposed to have defeated...
What annoys me is that book. You would think that, thinking he had sacrificed himself to save the world, they would have spread the real story and reason he acted like that. Yet that book was clearly either written for someone with a grudge, or that did not bother doing the research.
