How do you feel for wild mice, who typically have short lives of borderline starvation before they are eaten by a snake, bird, or other predator?
replyShould hunter gatherers be thankful if we kidnapped them and tortured them to death in our labs?
replyWhat about people from Gaza?
Is it acceptable to do human testing as long as you pull the humans out of say east Africa during a famine?
These examples don't work. Hunter gatherers didn't suffer, and the other two are in outlier bad situations. Set them free in a stable situation and they'll live happy lives.
replyIf that description of wild mice is accurate, there is no happy free life. The baseline is very different. I'm not going to try to say how that should affect the rest of the ethics, but it's an important point to consider, and not as easily dismissed as your examples would imply.
