"We can only guess what drove him to such a tragic end, but it is a fitting demise for a man whose professional reputation is based entirely on a lie."
What a terrible thing to say about someone who is dead, regardless of whether they stole anything.
I read once a quote, I think by some senator in the 1800's, who responded to someone's attack on a man who had just died by saying : "Sir, when God puts his hands on another man, I take mine off."
That's a bad paraphrase, but the original quote was pretty good.
Generally the done thing in those cases is to simply not say anything at all, unless the person in question was some kind of notable who belongs in a history book, which isn't really the case here.
Strictly speaking, I agree with you. I ultimately don't care how I'll be remembered since I'll be dead, but life itself is much more fun when you aren't hated while living it, at least not by too many people. Also, for those people with a conscience, just the personal knowledge that one's success is "based on a lie" might well be enough to sour the flavor of that success.
From what I've read, there's no evidence that Katz drank himself to death because he was overwrought with guilt caused by "stealing" ARC. I feel that if someone takes an existing program and re-writes it entirely in a more difficult language and creates very tangible improvements to it, it's not simple theft. Almost nothing is that black and white.
Katz was, apparently, a guy with no friends who spent most of his time with strippers. I would probably drink a lot, too.
In a purely selfish mindset, think of your heirs. I assume you care about them? It negatively impacts their happiness and wellbeing (acceptance by peers) if you happen to ben a truly-reviled human being.
You can't hurt the feelings of the dead. I would sooner speak ill of a dead person than (an equally deserving) living person, for multiple reasons, first among them being that people can and do change.
