But listening to what he has to say towards the end here, even now after all this time, all I hear is:
He expresses remourse that he wasn't smart enough to press the right buttons to get the right responses out of everyone else.
He regrets that this miscalculation resulted in him failing to achieve his goals.
He litterally only says it that way. Not "It must have really sucked dealing with me. What a dick I was...", just "it was a mistake not taking other people's feelings into account"
The kernel credits are interesting.
That is a little more possibly genuine. It seems genuine, that he really wants them to be acknowledged simply because they should be and not because he calculated that it makes him look better.
But I don't know how materially valuable that might be for parole reasons. If it might make even a little difference there, then you can't trust it, because this is not a benefit of the doubt situation, this is a known entity who has already manipulated others many times, and so now it no longer matters that an act might finally be genuine this time, it makes no sense to assume that in this case.
But in my own example of pressing buttons, I try not to shit on behavior I want to see. All else being equal I want to just accept that small act as good on it's face and leave it at that.
Also because it seems petty not to, because he gets nothing else at least from me, forever, because his wife can't be forgiven and redemptioned back to life.
