One of the tragic things about Revenge of the Sith is that they cut out half of the entire reason Anakin turned to the dark side.
He turns on the jedi because he wants to save Padme, but in that moment he is still doing what he believes is necessary to save his wife from certain death.
What actually seals his fate and *causes him to turn away from everyone, even those he loves* is seeing Obi-wan arrive on the ship with Padme, because to him, it confirms that they are having an affair.
But why? Is that really all it took to get him to doubt his wife loves him? Showing up on a ship together?
No, the reason he calls her a liar and shouts "YOU'RE WITH HIM!" before nearly killing her is that there's an entire subplot of the film that was cut.
In this subplot, Padme is secretly setting up the beginnings of the rebel alliance. She has figured out that Palpatine is an evil dictator and wants to remove him from office. She doesn't tell Anakin about this, aside from vaguely hinting at it when she says "have you ever considered that we may be on the wrong side".
Palpatine figures out what Padme is up to, but instead of directly cracking down on the rebels, he uses the fact that Padme is keeping a secret from Anakin to drive a wedge between them. Anakin knows *something* is up with her, but not exactly what. Palpatine exploits this by implying on multiple occasions that Padme is having an affair with Obi-wan. He tells Anakin that this is why he was kept off of the council.
From Anakin's POV, Obi-wan is keeping him down, stealing his girl, preventing his ascent to Master (and from accessing secret info that only masters are allowed to read), and even stealing his valor by taking on General Grievous alone despite being the less powerful jedi. And the Jedi Order is enabling him to do so.
So, when Obi-wan shows up on Mustafar with Padme, Anakin "realizes" that he has betrayed and killed children to protect someone who didn't even love him. He's lost everything and been played a fool.
Palpatine seemed to be the only person in the universe who wasn't lying to him and trying to keep him down. Or so he thought.
It's been a long time since I last played Destiny 2. I still remember all the times my friends and I did weekly resets on all of our characters from D1 all the way to Forsaken... Oh Destiny... the news from today make me want to relive those days all over again...
I booted up Destiny 2 after 2 years of not playing... my god... so many memories made and my reaction to just seeing the travelers whole again just took my breath away and I realized why I love this game and its lore
