This post shows the very worst of the equation, and they will bring up the best, maybe some people that couldn't walk that now can, or some psychological disease for which this contributed to the cure.
They will probably bring up numbers like, this damaged hundreds, but will benefit hundreds of thousands.
This is not the first time society accepts such a compromise. There are innocent people in jail serving life sentences, because every criteria will have false positives. We can undo this wrong right now, we just have to let everyone out of prison.
Only as a selfish species we find this positive.
Most Nazi human experiments were just atrocities without scientific value but the Dachau hypothermia valuable data. Is that justified? https://www.nejm.org/doi/full/10.1056/NEJM199005173222006
Personally I don't thinks these questions have good answers and thus I think we (as society) should adopt a values first mode while critically reflecting about where our values will lead us. I understand the consequentialist appeal but it's deeply flawed as expectations are made up and it's just too easy to justify anything.
What worries me about Neuralink is that I don't think the experiments are motivated by base research or will benefit humankind or any kind besides Musk and his partners. It's a private company based on hype. Best case scenario it's just propaganda.
However I don't think they should be entirely dismissed. Specially if at some point the weight on each side of the balance differs by enough orders of magnitude.
As for things changing over time, that has already happened since the rise of ubiquitous communications. Social attitudes have changed drastically since the 1980s.
I think this type of research might bring us a level forward for people who are blind or have parkinson's or other things and that this also might be the way for us humans to evolve further.
If the results of this type of research is fruitless, that will still be a discovery.
I do justify the experiments and death of those handful animals through the type of research, the goal of it and the importance.
I'm fairly certain in 50 years we'll look at the way we treat highly intelligent and social primates not to mention other animals the exact same way we've looked at the atrocities and ethical breaches in scientific research of the past.
I'd actually like to see an interview with the people who have to witness these kind of Frankenstein experiments first hand and how they justify it.
