Same reason you didn't use your brain to think your question through
Why didn’t Thanos just use the infinity gauntlet to produce infinite resources?
marvel knew general audiences would be to stupid to understand the desires of a titan (that being inlove with a concept) so they decided to give a stupid reason for him being the way he is
Why didn't he use the infinity gauntlet to get people to start living sustainably without killing people while giving resources to those who need it
because he's a jackass, you jackass
Infinity War's DVD extras explains it. Thanos wants to be proven right. He wants a pan on the shoulder and to be told that had his people listened to him and not basic population dynamics, they'd be alive. In the end, it's all about self-gratification.
When he snapped his fingers, he should have made two identical universes, each with one half of the population who thought the other half had died.
Imagine seeing Avengers Endgame from the other universes perspective.
>the avengers murdered an innocent war vet farmer who wanted to live the rest of his days in peace
is there something you fail to understand in the word "infinite" ?
>infinite food for Galactus
Why didn’t Thanos just use the soul stone to find out the wisest solution?
