take a look at Johnson and Johnson, their employees and shareholders are very well off, their profit in 2017 was 16.3 billion dollars (around 1/4 of their revenue) and I'm sure you have your own objections towards their business model when you say they're in part a force of evil. it's not illegal, but there are big moral dilemmas here,
I find it very sad that a drug selling company is among the most profitable in the world.
