On the subject of pain-moment badness,
If pain becomes more common (even if it gets forgotten), then at any given instant I’m more likely to be in pain than otherwise, which I would consider worse, even if I forget it afterwards.
So torturing people then removing the memory is a bad thing, as a general rule.
I’m still a bit shaky on how that affects question 2.
