Life is self-emerging. There is no higher or predefined purpose. You can live without one, or define your own, which may or may not change over time.
Regarding death as the ultimate conclusion; you can make of it what you want. You can consider what you leave behind. You can see life itself as worthwhile, without a need for an end-goal that follows after.
You say that you believe most people can differentiate between good and bad, but note that people often think they are doing good while doing evil deeds. The human mind is exceptional at reasoning even against logic or facts when it is to preserve a positive self-image. You mention being brainwashed; often, people "brainwashed" themselves.
Defaulting to tolerance, goodwill, and expecting good is a good start, but tolerance must end somewhere. Excessive tolerance will inevitably lead to it being used/exploited. At various costs.
Flexible morals make sense. Different contexts require different adaptions. Considering them flexible or not may also be a matter of not including enough data points/context that sources moral conclusions.

Recently, I've been mindful of how long fights are in movies.
Sword fight? Fanning at each other, crossing and smacking swords. Maybe even walking around each other. I don't think that's how a real sword fight would look.
Fights where it's mostly talking. Talking and talking. Nobody would fight like that.
Fist fights without a smack and dead. It's fancy movement - only because of the shaky camera and cuts of course. Give me back Jackie Chan or smack them once and they fall over.
I also dislike noticing the wire-guided movements. Fast acceleration and you can see them balancing in the air lifted by wires. Wires removed after-the-fact, but it's such unnatural movement.
And of course, the classic gunfight where nobody hits anything.
Or any monster chase or fight. If a giant monster chases you it's faster and instant-kills you. But not in movies.
