You are talking about a different guy. Dr Mengele is the guy who tried an UNhuman things.. but not with germans. He use a jewish guys for this. There is a amazing documentary series on National Geographic about it. You can check it if you want to get more knowledge about it.
I am not saying if this is good or bad. What I am saying is that this part of the History. Maybe after 100 years our grandchildren will think about us that we are very stupid to believe in Covid-19 , but this is the current life.
I know who is this dude, but I mean also drs nazis made experiments anyways all I said is being part of the history or no, is not something you could be proud of, if you are then there is something wrong with you
