Ok why do we humans have to take responsibility?

Why can't I declare myself to be a "company" (which is only responsible to shareholders) and then never take resosibility for my actions? Why are we humans burdened down with moral responsibility while companies can jerk that responsibility because .... well because they are a "company".

After all, companies are made of what? People. People make companies and people take responsibility but somewhere along the line, these responsibilities can be dumped.
