I could just as easily come up with a post hoc story that says that the reason that he has never come forward to claim credit is out of extreme embarrassment about the size of the fortune he lost, and that this is evidence that he does care about the money.
The entire conversation started because someone pointed out that just because Satoshi said something doesn't mean it has to be true (although they made that point in a rude way.)
The vibe I am getting from your responses is: 'satoshi is a saint, everything he said has to be true, and any attempt to point out that we have little evidence about Satoshi's character is a baseless smear.'
I am sure that is an inaccurate and unfair characterization of what you are trying to see, so please correct me as to where I have it wrong.
I thought you were defending the a comment claiming satoshi was being malicious. I would've done better to search for a more charitable interpretation.
If Satoshi did stretch the truth or lie in that quote, I would be inclinded to view it as motivated by ideolatry rather than greed. However, any speculation as to motives is fairly pointless given the lack of information.
For all we know, these coins have already been "burned"
like I said, the best you can do is burn the private keys, but that isn't verifiable - you can't prove something doesn't exist
