Hopefully this isn’t considered spoilers since I assume everyone has seen this movie.
But the powerful ending of Schindlers List where he breaks down in tears about how he could have sold his car or his gold pin to save “just a few more”. For some reason it got me thinking, when he’s breaking down like that, doesn’t he realize just how many people he could have saved if he just made actual working munitions instead of having to bribe other munitions factories to then get their munitions and pass it off as his own. I get it, “If you’re making actual munitions and those munitions are killing others it defeats the purpose of then saving people” but the fact that it’s been proven in combat that something like less than 1% of the bullets are actually used to hurt/kill people and the rest are either misses or destroyed in some way or another, it really seems like he could have saved millions and just saved a lot more Jews.
I’ve heard alternating things about if in real life Oskar actually did sabotage his own munitions so I don’t quite know the truth about it fully but it really makes it seem like he should have just made actual munitions if he wanted to save the most people total.
Or to put it another way, manufacturing faulty munitions would speed Germany’s defeat, which potentially would save more lives than extra money ever could have.
Also, the “purchase” of the Schindlerjuden took place before he relocated to Brünnlitz so any money he saved there would have been irrelevant. Even if there were any local Jews (doubtful), there wasn’t a Goth whom he knew well enough to hornswoggle into releasing them. His regret was that he’d blown so much on high living in Kraków.
Anyway, as already posted I think he was remorseful of his extravagant lifestyle while people were still being exterminated. Jewelry, cars, fine dining and clothing while those he meant to save lived in squalor and were still being murdered. Giving up some of his posh lifestyle may have done more than any of those other actions mentioned.
On “Dr. Katz, Professional Therapist”, a patient tells him that he’d just seen Schindler’s List, adding, “To tell you the truth, I didn’t think it was that funny”.
