The Girl in the Red Jacket

As I've sure you've all noticed by now, there's this reoccurring character in Schindler's List that seems to have no explanation as to why she exists or is so emphasized: The girl in the red dress. I wanna ask you guys, why do you guys think the girl in the red dress is so emphasized in this movie? Why does she exist? Why is her jacket in color?

I have my own personal theory about this. I think the little girl is symbolic of the SS, the war, and the genocide of the Jews. The first scene we see the little girl, she walks amongst the SS, almost invisible to them. She's in a jacket that's colored red when the whole movie is in black and white. The color red is normally symbolic of death, blood, war, and evil. Childhood represents innocence. Synthesizing all these things, I personally think the little girl is a symbol for the SS believing that what they're doing is innocent, not hurting anyone at all, however, that "red" follows them everywhere, almost invisible to them. They first think that putting Jews into ghettos is innocuous, but really, death, blood, and evil follow them everywhere they go like a shadow. What they're doing is not innocuous, but instead causing people to die.

The girl returns a second time, this time, after the SS are given orders to burn all the bodies of the dead Jews in the Krakow work camp. The girl is shown dead, in a wheelbarrow full of other dead bodies, still in the red coat. In my opinion, this is Spielberg telling the audience that the Nazis have finally realized that their innocence is dead. They are no longer just putting Jews into work camps, but instead, killing them off systematically. The Nazis know they are losing the war, and with that knowledge comes the realization that what they are doing is looked down upon and shamed by the rest of the world. They might have realized that what they've been doing is horrific. The dead girl symbolizes this realization.

But, this is only a theory of mine. I don't know if this is accurate or not, and there might have been some things I missed or skipped over when making this theory. What do you guys think of the girl in the red jacket?
