It would be unfortunate to have a Skreli situation where we just randomly take out the one with the most punchable face rather than dealing with the structural issues that have created a whole industry doing what he was doing.
Shkreli was by no measure a dominant player in anything other than the tiny niche he exploited for a short time.
Sure, he just had the most punchable face.
Shkreli messed up by continually taunting US law enforcement. He probably wouldn't have had the book thrown at him if he wasn't constantly talking about how great it was to be an evil capitalist, and instead gave the mealy-mouthed platitudes that every other CEO of pharma companies does.
Yep, he's the poster boy for "play stupid games, win stupid prizes."
