Yeah I knew about Death in the comics, but I thought it was like a additional thing, since they've already hinted at the same thing in the MCU in his first appearance in Avengers 1. I assume we might see her in part 2?

All the explanations for not "making more resources" seem pretty silly to me. From a hard physics standpoint, really anything thanos does with the gauntles violates all laws of nature and basically he can do whatever he likes. Even if he was somehow limited to using existing energy, but was miraculously able to harness it immediately and from any distance, he could've still easily fixed any energy problems any inhabited planets might have. If the MCU is at all like the real universe, there's so much high-energy garbage (stars, black holes, quasars) floating around everywhere, he could've just redirected all that energy to make free milkshakes for everyone forever. I just don't see how obliterating half of every sapient being would be any easier than to just give people resources. At the very least, he could've just taken a much smaller amont of people than 50% and thrown them into ovens to mass-energy convert them into usable energy for the rest (that would've made for an interesting scene). Also, didn't Tony Stark just fix the whole energy problem on Earth with a glowing donut? Why can't thanos give everyone glowing donuts? Also, I thought the Gauntlet was broken because Thor's attack hit right as Thanos was using it.

And yes, of course you're also right that it's obviously much more likely that half the population of a planet vanishing from existence in a moment will lead to the other half dying shortly after than anything good coming from it. All this is so stupid that I'm actually wondering if it's all a deliberate ruse that Thanos is pulling for some reason and "courting death" has been his only motivation all along?

I really liked the movie. Thanos was a badass and I really hoped they'd actually let him win in this one so I was really happy to see it.

"The universe is finite. Resources are finite. Therefore I must wipe out half the universe to fix overpopulation. Proceeds to alter reality at will, break all laws of physics, generate unlimited energy and warp time using the things literally called "infinity stones".
