The tricky thing with a case like Shkreli's is that what you are being tried for, and what the jury wants to put you into jail for, are potentially different things. Very difficult to extricate. If he was in court for grand theft auto and he had a perfect alibi, he still might be found guilty just because it's an opportunity for the jury to deal out some "righteous punishment" given the opportunity. Is this judiciary morality and ethics? Is it a greater-scope of ethical absolution? It's really hard to say. The court tries you on a specific set of bullet points, and if you don't get convicted you're free to go, but the emotional closure may not have happened.
At any rate, I don't think "Punishment for the Crime" is the only adage we can continue with in our modern society. We also need to make provisions for rehabilitation, amelioration, healing, and in general promoting the psychic health and welfare of people who are deemed "perpetrators" instead of labeling them as lost causes (until of course they re-emerge into Society and the issues have been substantially compounded).
