I understand he did drugs to win in competitions. I get that people feel deceived. It's not okay to do what he did. He stepped up as an icon and used the fame he was getting to do some great things. This is not a justification at all, just a little perspective as to his possible motives. He used his evil power for good. In some ways.
I don't see how he compares to a multinational corporation who is mass producing invasive species and then destroying the farmers whom they've invaded.
This feels like a good debate topic, not really a question answer topic. Perhaps it belongs on the forums.
