Many people have strong morals, and might resist profit-maximising behaviours, but they will be outcompeted and replaced by less scrupulous people. There is actually no sharp difference between a person and a one-person-company, but: to the degree a company is really a company and not just a person, it is amoral. If you disagree, please point to a moral backstop that would prevent any company from taking immoral acts. A few exist, but they are invariably resisted by the most powerful companies. Sorry to be the bearer of bad news.
