It's a bit more complicated than that. When somebody's only goal/pleasure is to make money, it's very easy to lose sight of ethics/empathy, in particular of things in the grey areas.
And note that with "grey areas", I mean things that would be repulsive to ordinary people, e.g. patent trolling (is it illegal? no! does it make lots of money? yes! is it unethical? what do you mean? :-)).
