While there is an obvious issue with Musk clearly being in a position to know that this was going on and not shutting it down, it saddens me that there was (is) a team (multiple teams?!) of highly qualified medical scientists that were (are) psychopathic enough to actually do this horrific shit over an extended period of time. Everyone involved should be stripped of everything dear to them and placed in a small dark hole for the rest of their miserable lives.
You read the account of what those animals went through and didn’t feel sick? If that’s the case then whatever sky fairy you’re thanking has not helped you become a good person. Maybe seek some help to deal with your lack of empathy?
Animals will always play a part in medical testing but effectively torturing a number of animals for months on end is well shy of a well constructed ethical experiment.
