I'm not sure I'm convinced about the first paragraph. Why must it be fitting to want utilitarian ends? I mean couldn't you just give the same answer as to the aliens who torture people if you are utilitarian (tho obviously not about consequences I just mean shrug and say it's not a theory about what you should want at all just a true claim about a certain kind of moral fact about which worlds are preferable).

However, I can endorse the second paragraph.
