No Stupid Questions

If you want to try and rationalize it, I think he might say that the psychological scarring is necessary for all existing societies to change to more sustainable models, or risk another such culling in the future. Due to exponential growth of life, doubling resources, especially while societies continue to abuse those resources wouldn't probably wouldn't do anything long term (in his mind).

I am skeptical if such psychological damage can make enough long term inter generational impact, but hey it's a theory.

Maybe he did

Jesus-Zombie-Christ....Fucking vanilla! How do you even get hard without wiping out half the life on a planet?

I love how this whole premise never gets questioned. By anyone. None of the super smartest people in the movie were like, "no that won't work." The premise just gets accepted as true, but it would be bad.

"I'm going to eliminate half of all life in the universe" hey thanos did you know that scarcity in modern society isn't driven by population at all, and is in fact an artificial condition imposed on the lower classes by the ruling class that hoards those resources?

No its just like, "well killing people is wrong but it would probably work, people might be sad though." No Disney, fuck you. Don't let people believe this shit. Thanks for your endless support for cultural fascism, ya fucks

The short answer is that they had to come up with something more palatable to a movie audience than “I’m evil and have a crush on the literal Lady of Death.”

Back on Titan, Thanos told his people "you need to kill half the population to save our civilization from disaster." The people of Titan dismissed Thanos as insane. Thanos, being actually insane, decided he was going to prove he was right by going around massacring halves of populations.

In other words, he's not doing this to actually help anyone, he's doing it just to prove he was right. Solving the universe's problems by other means wouldn't do that so that's not an acceptable outcome for him.

I think what was missing was his obsession with Death. The MCU didn't include his infatuation and Death's hold on him. He wanted to impress her and she held him to it in the comics.

In the comics, he was trying to impress his girlfriend, Death.

The comic had better writing. Thanos killed half the universe so he could fuck Death. He thought she'd love that shit since she's, y'know, death. I'd do the same for a goth girl.

Because the only way Marvel movies know how to ratchet up the stakes is having more and more people die.

Because it’s a pretty dumb story at its core. Because they wanted the “worst villain” but couldn’t come up with something more interesting or intelligent than “misguided environmental terrorist.”

"When your only tool is a hammer, everything looks like a nail"

Dude just wasn't very smart

They don't call him the Sane Titan.

And he's purple because he's an alien who Jim Starlin gave purple skin.

What will the movie be then? 3 hours of the Avengers thanking Thanos?

same reason expanding the highways doesn't relieve congestion. Induced Demand.

FWIW, he basically did double it. I mean, if you have x resources for a population, and you halve the population... they now have twice the resources...

Comic book universes have never been great on internal consistency. Most technologies and superpowers we see would have ushered in a new golden age for humanity.

You won't get a satisfying answer to this. It's because the story had to happen. He's evil.

Imagine snapping half the population and they were all conservatives that got snapped, we will actually double our resources.

1. Because he's an insane villain with a fixation and a lack of sense for mathematics; halfing the population doesn't help much and delays everything for a few generations max.
2. Hulk states in Endgame that it's mainly gamma radiation, stating it's like he was meant to use them. So Thanos seems to have similar resilience to gamma radiation as the Hulk.
3. Seems to be an affinity type of thing - in "Guardians of the Galaxy" the stone annihilates normal people trying to use it (The Collectors Servant/Slave for example), but since Quill is a celestial hybrid, they can use the stone without dying.
   4)They were destroyed by Thanos at the beginning of "Endgame" - it's the reason they have to go back in time to get them, and place them back in the past afterwards, so that the timeline doesn't get fucked up.
   5)Because space aliens can be whatever color they want to be :-)

On doubling the resources, I think that falls into the "obvious, but wrong, answers contain the word 'just'".

let's say you double the resources. without being specific, you just doubled light and the mass of the sun and the mass of the planet and killed everyone.

ok, let's say you get more specific, drinkable water. double it. in place? there goes every pipe and reservoir on the planet.

plant nutrients? now the concentrations could be toxic for the plants and now they're dead.

double the asteroid belts? a lot of these species are space faring, after all.

each species and planet would need a custom solution, and that takes work. In addition, the main issue isn't the availability of resources, it's how they're allocated.

just doubling all the resources could end all life in the universe.

With all the food we throw away now, it's not a resource peoblem anyway. And that's too much logic for a Disney movie
