I was unable to empathize with this view when reading 3WC. To me the Prime Directive approach makes more sense. I was willing to accept that the Superhappies have an anti-suffering moral imperative, since they are aliens with their alien morals, but that all the humans on the IPW or even its bridge officers would be unanimous in their resolute desire to end suffering of the Babyeater children strained my suspension of disbelief more than no one accidentally or intentionally making an accurate measurement of the star drive constant.
To me the Prime Directive approach makes more sense.
As an example outside of sci-fi, if you see an abusive husband and a brainwashed battered wife, the Prime Directive tells you to ignore the whole situation, because they both think it's more or less okay that way. Would you accept this consequence?
Would it make a moral difference if the husband and wife were members of a different culture; if they were humans living on a different planet; or if they belonged to a different sapient species?
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
