Last week, Goldberg set the internet wrestling community on fire when he appeared in a video game commercial promoting WWE 2K17 during that evening's episode of Monday Night RAW. The company had been posting cryptic tweets in the days leading up to RAW, teasing that something or someone was inside a mysterious hatch. That someone turned out to be Goldberg, and after the hysteria finally died down roughly 48-hours later, it was reported that Goldberg had only signed a deal with 2K Sports, and not with WWE.

In several ensuing interviews since the commercial was released, Goldberg let the door stay open in regard to the possibility of returning to the squared circle one day. However, he and WWE have had a tumultuous relationship for over a decade, and negotiations have yet to even begin. This one caveat remains, however. Goldberg would not have been allowed to appear in the video game without the approval of Vince McMahon.

Incidentally, Lesnar just admitted that his decision to step away from the UFC has haunted him every single day since he made it, but his regrets were recently resolved with a one fight return to MMA at UFC 200.

The Goldberg/Lesnar match is widely viewed as the most disgraceful match in WrestleMania history with information about both men leaving the company after the event leaking to the public before the event adding to the debacle. Surprisingly, though, neither Goldberg's decision to walk away from the WWE or his match with Lesnar at Wrestle Mania XX rank as his biggest career regret.

The former star spoke to Romain Mahut to promote the video game and revealed what his one huge regret actually was (Thanks to Wrestling Inc for the transcription).

"I wouldn't have kicked Bret Hart in the head. I respect Bret. I look up to Bret. A tear comes to my eye when I even think about it. For an icon like him to have his career cut short by a mistake or an accident by myself is almost impossible to deal with. So that's truly to me, not to be selfish, but to make myself feel better, but, at the end of the day, I just wish I could take that back."

It was one of the major catalysts forcing The Hitman to retire. Nine months after the kick, Bret cut a scathing shoot promo on Goldberg, and even wrote a column for a newspaper where he said Goldberg had a tendency to injure everyone he worked with (Bret is currently mired in a verbal spat with Seth Rollins for a similar issue in which Hart says Rollins has been reckless). The Hitman has since scaled back on his criticism, and Goldberg has maintained his remorse since he's been away from the ring.

One wrestler who has made headlines for all the wrong reasons lately, but at his peak was drawing comparisons to Goldberg, is Ryback. His brute strength, signature finisher, squash matches, and little need for mic work had fans in many arenas chanting "Goldberg, Goldberg!" during Ryback's time on-air. Goldberg is just appreciative that people still remember who he is.

"At the end of the day, I'm appreciative that people would make any kind of comparison with me and somebody in the current [professional wrestling] business in a positive light. And as far as what I think of Ryback's concerned, I mean, more power to him. I hope nothing but success to him, but if he ever was in the ring in front of me, he [has] got a serious problem."
