Absolutely. Nobody involved in the scharade should be able to just walk away now because he's dead. Let alone be able to hide behind the "tragedy of his suicide".
Or even worse, cynically use his suicide as evidence that he wasn't actually a lying liar and that all of the stuff he claimed was actually true.
And he was owed either care or the decency of not being allowed to get away with lies. Depending on what actually he was.
