In the actual movie thanos' plan wasn't even necessarily to destroy half of life. His thing was on his own dying world saying "hey if we don't kill half of people the world will end, we need to have a fair lottery to determine" and then the good guys say "nah, lets not" and then everyone dying. He then found a second world with the same issue (gammora's world) and did it then everything on that planet was great and it became a paradise.

His original plan with the stones was to be that sort of hated necessary evil, cruel but fair, a force of nature balancing things. It shrunk down to flat "kill half of everyone" because he got stabbed by the avengers and lost so he enacted the claim he had said earlier that with the stones he could have saved his planet "with the snap of a finger". If he was let to enact his whole plan it would have been decisions LIKE that, not just literally that one only.

Which is actually a fairly interesting trolly problem sort of character. He was a savior willing to sacrifice to be the most hated man alive. (but the story got to side step it as a question because he did a "kamikaze move" when defeated and only did a much more overtly pointless and evil simplified section of the plan of "be a force of balance")
