Good points. I'll add that the majority of his funds came from illegal pharmacy that was selling drugs people could get from local doctors but might be turned down. To put that into perspective:

1. It's legal to get the drug if a single doctor agrees you need it, you can afford to pay them, and you can afford to pay for the drug.

2. It's illegal to get the drug if Le Roux's doctors do it with their methods at probably lower prices.

So, just being poor means you can't get medicine. That's illegal. But immoral? The law itself sounds immoral here. Further, the law relegates the decision to any human with authorization to prescribe drugs. That makes it quite arbitrary given their range of opinions and actions. So, there's no connection between the law and morality here except perhaps an immoral transfer of money from companies that benefit from the situation to middlemen that pass it to lawmakers. Sounds... like Le Roux's network a little bit, eh? ;)
