An abhorent attitude caused by flawed reasoning about counterfactuals. I have bad knees. It would be better if I had good knees or if my parents had taken a test for bad knees (which exists in this hypothetical but not reality) and aborted babies with bad knees so they could have a child with good knees. If I could get my knees fixed I would. My life is nonetheless valuable and productive and killing me would be bad. None of those statements are in conflict. Improvement is change, yes. But that doesn't mean it's bad. Giving everyone infrared vision might be considered destroying non-infrared vision people and their culture but it's a positive overall (so many less burns!).
