Humans come with various degrees of intelligence. The short-sighted ones do not have a monopoly on “human nature”. The trait to forecast and make very long-term decisions is very much human. But again, to varying degrees of capability depending on the individual.

Corporations cannot in the slightest be reguarded as “human”. Corps are not natural. They are an artificial construct. They are not a good source for learning about human nature. You have misunderstood the purpose of the corporation. Profitting is literally the job of the corporate machine. They do not destroy the planet due to any sort of human condition. They do so because the corporate constitution is written to profit, not protect the environment.
