It doesn’t pan out or make sense cause Marvel changed his motivation. His original motivation is and always will be gaining the Bring me Thanos Bucky Spider Men Black Widow Captain America Groot shirt. But marvel thought this way worked better movie wise honestly it would have been cool to introduce lady death. I mean she is the reason he is who he is. Then by your logic, he must have had “physically” wiped out half of the animals, plants, microbes, and all those other things you are accusing him of. That’s seems illogical taking what he said word for word..don’t you guys think?

I think it all comes down to determing what Thanos meant by “life” and Bring me Thanos Bucky Spider Men Black Widow Captain America Groot shirt. If he meant that intelligent life is exhausting the resources of the Universe I think it would be safe to conclude that animals, bacteria and plants are not a part of his equation as their function in this case would be to sustain that form of life. There’s no evidence in the movie that he eliminates non sentient life. Groot banishes, but none of the trees and plants around do. He definitely had some non random involvement in who was chosen.
He spared Tony and comforted him with the fact that half of humanity would be left on Earth. He promised to spare him from death before the snap, but obviously knew it would be a dick move to promise Strange he would be spared then go ahead and snap him away. I think it’s safe to read into this exchange on Titan to get an idea of what Thanos is really thinking.
