Oskar Schindler, throughout the movie and in Real Life.
The Goleszow transport wasn't in the movie but deserves to be mentioned. In January 1945 a frozen train with about 100 Jews who had been traveling for weeks arrived in front of Brünnlitz. Many were already dead and it was clear that those who were alive would never be able to work at the factory, but Schindler employed them as "essential workers" and many survived.
It's a quietly powerful moment when Schindler and Stern share their first drink together as friends.
The tear-jerking end scene where the real people Oskar saved place stones on his grave (a great sign of respect for the dead) accompanied by the actors who portrayed them, concluded with Liam Neeson laying a rose in the center.
Schindler hosing the train cars during an especially hot day to help the Jewish inside if only a little. Goeth at first mocks him and laughs with his fellow Nazis but soon just sits in bewilderment as if he honestly can't understand the act of selfless compassion.
To quote Stern: "The list is an absolute good. The list... is life. All around its margins lies the gulf."
If any moment of the last half-hour of this movie were in another movie, it'd be a clear CMOH, from when Schindler informs the rabbi that the Sabbath will be recognized to when said rabbi gives a letter to Schindler as he's about to flee the camp that explains Oskar's heroism and tells him, "Every worker has signed it."
Not in the movie itself, but Spielberg's refusal to accept a salary for this movie, stating that it would be "blood money", definitely qualifies.
Just after Schindler yells at Regina Perlman to get out of his office and goes downstairs to rage at Stern that his factory isn't a safe-haven and it's all about making money... and then gives Stern the names of Regina's elderly parents so they can be saved.
A bit later, as the Perlmans arrive at the factory...Regina sees them enter; the expression on her face says volumes.
Early in the film, Itzhak Stern is placed on a transport to almost certain death and Schindler shows up at the Krakow train station to fetch him, coolly explaining the potential danger to "production". Despite his seemingly tranquil bluster, he clearly starts to panic when he spots Itzhak in a moving train, banging frantically on the doors of the cart. The facade is cracking . . .
A very small one in the scope of the film, but Oskar promising his wife that he will never cheat on her again, just her smile is so beautiful.
Near the end of the film, there is a poignant scene where Schindler expresses remorse over not saving more; on how he could have traded more just to save one more...just one more...
Producer Branko Lustig's acceptance speech for this movie's Best Picture Oscar Award began with these words:
When he ended his speech, he got a standing ovation, which almost never happens during a Best Picture speech.
Gene Siskel's first words on the film in his and Ebert's review: "There's something I have to say to Steven Spielberg, both as a film critic and as a Jew: thank you."
The scene where one of the workers donates his gold teeth to be melted down into a ring as a thank you present to Schindler for saving their lives. And the inscription on the ring: "Whoever saves one life saves the world entire."
There is a twisted example from Goeth. Having grown fond of his Jewish maid, Goeth is unwilling to send her to Auschwitz and secretly confides in Schindler that he would like to take her back to his home. When Schindler points out that such a plan would be impossible, Goeth admits he knows, which is why he'll just take her out into the woods and shoot her instead to spare her from the horrors of Auschwitz.
At the end of the movie, Oskar tells speaks with the guards about their orders to exterminate all the Jews in the factory, and gives them an ultimatum- follow their orders and kill them, or leave with a clear conscience. Every single guard turns around and leaves, and Nuremburg Defense be damned.
Tear jerking as the armless man death was, he died believing he was useful for someone.
