> Prosecutors argued that Shkreli lied to investors in two hedge funds and the pharmaceutical company Retrophin, all of which he founded. Shkreli told investors he graduated from Columbia University, that his hedge fund was large and profitable, and that he had hired an auditor, they said. These were all lies, according to prosecutors.

"He lost everything in MSMB Capital after a bad trade in February 2011, and hid that fact, sending investors statements for more than a year and a half showing strong returns — even though the fund didn’t trade after that month, and had no assets."

He's not charged with anything related to the drug price increases.

This trial was not about him raising drug prices but rather about how he deceived investors. He lied to them and used illegal business practices to cover things up

The reasons he is hated aren't the same as the reasons he is on trial.

What was morally abhorrent? Raising prices to insurers to perhaps fund other stuff, while giving away medicines to people that had no way of obtaining it (no insurance)?

If anything he should be lauded for proving how broken the medical system is (why could he so easily buy a monopoly on this product?), while not killing anyone.
