I've seen similar things. Besides many experiments not being remotely worth the harm they cause (poor design, niche topics without applications, dead end checking-all-the-boxes, etc.), they leave a mark on the people who conduct them. Some leave that sort of research out of distaste or disgust, and some become callous. It struck me that it inculcates an inhumane indifference to suffering. And numb scientists. It ultimately damages both the people and the science. Yet incentives (monetary, career progression) can push people past boundaries, and with time, erase them.
