Add to that their particularly hostile approach to patent applications (100+ on Humira alone), and to me it appears that AbbVie perhaps has a vested interest in stifling innovation and charging large amounts of money for their products "because they can".
The point about the pharmaceutical sector’s profit margins is about the sector more than it is individual companies. Minnows that make supernormal profits expand and as they expand their profit margins decline because they use up the most profitable opportunities and move on to less profitable ones until there’s nothing left. This last bit never actually happens because things change fast and general equilibrium is never reached but that’s the tendency. Large profit margins attract competitors and in the meantime allow those enjoying them to grow.
Re: “Profiteering”
According to the theory of neoclassical economics, anti-price gouging laws prevent allocative efficiency. Allocative efficiency refers to when prices function properly, markets tend to allocate resources to their most valued uses. In turn those who value the good the most (and not just the wealthiest) will be willing to pay a higher price than those who do not value the good as much.
