The most hated man on Netflix says he's changed

* This story may contain spoilers ...

A prosecutor in the Steven Avery murder case - the subject of Netflix's addictive new true crime documentary Making A Murderer - has given his first on-camera interview since the show aired.

As the former district attorney of Calumet County, Wisconsin, Ken Kratz is a key figure in the show, helping to prosecute Avery and his nephew Brendan Dassey for the 2005 murder of photographer Teresa Halbach.

Kratz has been villainised since the series debuted on December 18, thanks to his behaviour at several press conferences attacking Avery, and for a sexting scandal that's revealed at the end of the series.

In an awkward and off-kilter interview hosted by stand-up comedian Jena Friedman, Katz, dubbed "The most hated man on Netflix," says he's no longer the same man portrayed in Making a Murderer.

"I was a dick. Some of that was bravado that was necessary for the presentation of the case, but some of that was me.

"And I think it's important that people understand that I'm not that person anymore," Kratz tells Friedman.

Kratz also discusses some of the things he's been criticised for doing in the show, saying he would have toned down his press conferences when asked if he would do anything differently.

"There was a press conference that I had March 2, 2006, after Brendan Dassey was charged," he says.

"I was basically reading from Dassey's criminal complaint to tell the general public. The public has a right to know, that's why we're allowed to release that kind of information.

"What I would do now, much differently than I did then, was simply release the written criminal complaint."

Katz, who says he's received plenty of hate mail since the show aired, also says: "I don't sext anybody, much less victims of domestic violence."
