Companies do moral things all the time, being run by people and being, like people, tied to a community that they care about (often, to a degree) and which greatly affects the company. Without enlightened self-interest, and some broader self-interest, the society that provides customers, investors, employees, roads, security, markets, etc. - it collapses. The Middle Ages weren't good for business.

There are some additional rules for public companies, but in general, businesses can have whatever purpose "members of the company" (it's actually a legal term in many jurisdictions) agree on.
