It wasn’t enough to make money off the backs of dying AIDS patients — Martin Shkreli also told a former worker’s wife that his goal in life was to make her and her four children homeless, according to Brooklyn court testimony Tuesday.

The reviled “Pharma Bro’’ and former CEO of Retrophin was looking for revenge against Timothy Pierotti, who worked as a trader at Shkreli’s hedge fund MSMB Capital, because Pierotti refused to sell him back shares of the company on the cheap, Pierotti said in federal court.

Shkreli, strapped for cash, penned a long letter to Pierotti’s wife, lying: “Tim took the stock and ran off. … This is called fraud,’’ the man said.

“I hope to see you and your four children homeless and will do whatever I can to assure this,’’ according to the letter to Pierotti’s wife.

The letter — sent in January 2013 — was read out loud as the eccentric Shkreli grinned and winked at no one in particular.

Shkreli — who has been kicked off Twitter multiple times for throwing out false allegations — faces up to 20 years behind bars for allegedly using MSMB Capitol as a piggy bank to fuel Retrophin without investors’ knowledge.

After he was booted as CEO at Retrophin, Shkreli created Turing Pharmaceuticals, where he acquired the rights to a drug used by AIDS patients and hiked the price from $13.50 to $750 per pill.
