Rose is part of the aristocracy that’s dumb and acts naïve. We think she’s sweet and we love her for her careless ways.
But onboard the Titanic, she’s the true villain.
She falls for Jack, then lets him freeze in the ocean while she lays cozily on an enormous door. I mean there was definitely room for another.
So poor Jack is out there, freezing, barely able to speak. To make him feel good, she promises to never let him go. As soon as Jack dies silently in the ocean, Rose shoves his corpse into the ocean.
Oh, before leaving the ship, she steals a priceless jewel, that was given by his fiance whom she truly hates, and decides to elope with Jack. Totally a smart but selfish move. She keeps the jewel to herself for decades, remains tight-lipped, and tells no one of its existence.
Keeping that in mind, when a scientist finally finds the wreck of the ship and spends millions of dollars and years of his life searching for the jewel, she says nothing. Not even a single thing about the jewel.
The group of scientists, out of pure respect, invite her on the ship. She tells them the whole story about her time on the boat, her problems and qualms with aristocracy, and about her love, who we know to be as poor Jack.
Still, she tells them nothing about the jewel’s true location.
After hearing through her own story they decide to give up and leave. Then, out of nowhere, she does this:
Also, because she’s the only sole survivor from The Titanic, she can narrate the story the way she wants to, twisting the facts as per her will.
What if Rose was a Gold Digger obsessed with jewelry and preys upon rich men for their fortune?
Summing it up, Gold-digs her rich fiance into giving her the necklace, seduces Poor Jack, then allows him to die. Then she wastes another man’s hard work and money searching for a jewel she knows isn’t there. Then, she throws the jewel down there.
If I can’t have that toy, no one else can.
Then she continues her normal life having kids, grandkids, happily ever after.
