Pjeby, I'm unhappy on certain conditions as a terminal value, not because I expect any particular future consequences from it. To say that it is encoded directly into my utility function (not just that certain things are bad, but that I should be a person who feels bad about them) might be oversimplifying in this case, since we are dealing with a structurally complicated aspect of morality. But just as I don't think music is valuable without someone to listen to it, I don't think I'm as valuable if I don't feel bad about people dying.

If I knew a few other things, I think, I could build an AI that would simply act to prevent the death of sentient beings, without feeling the tiniest bit bad about it; but that AI wouldn't be what I think a sentient citizen should be, and so I would try not to make that AI sentient.

It is not my future self who would be unhappy if all his unhappiness were eliminated; it is my current self who would be unhappy on learning that my nature and goals would thus be altered.

Did you read the Fun Theory sequence and the other posts I referred you to? I'm not sure if I'm repeating myself here.
