When Schindler convinces the head and guards of Auschwitz, first by bribes, to let the women who accidentally got sent there free as well. Then he convinces the guards to let the children go by saying that their smaller hands are needed to polish the inside of shells. The kids never ended up doing that, and the entire factory ends up being, as the narration states, "the model of nonproduction".
This is something that was unique in the history of Auschwitz.
Schindler essentially legally, and calmly browbeating the guards sent to him into not interfering with the Jews at the factory at the end at all, noting that he would be paid, and they would go to jail, meaning it would be of no use to kill any of the workers.
Oskar inviting and reminding the rabbi he had working for him to observe the Sabbath once they entered the final factory. Said rabbi recited the prayers loud enough for every guard in the facility to hear, and yet had no negative repercussions whatsoever.
The ending, where Schindler is going over how to deal with releasing the Jews he has saved, and he talks to the guards.
Oskar Schindler: I know you have received orders from our commandant, which he has received from his superiors, to dispose of the population of this camp. Now would be the time to do it. Here they are; they're all here. This is your opportunity. Or, you could leave, and return to your families as men instead of murderers.
the guards slowly leave
One for Steven Spielberg, for just making the movie. For him, it was more than a movie, it was his heritage as a Jew.
For this movie, the credits are essentially a list of awesome people.
Spielberg himself gets a Real Life one for refusing a salary for this movie, as he claimed it would be "blood money". Doubles as a Heartwarming moment.
