I love Bret but it's not like he was fully healthy and one kick (that doesn't even look that bad) completely fucked him and made him retire. Listen to various Lapsed Chad podcasts, they love Bret too but they openly talk about how he was carrying head injuries even before he went to WCW, that 97 was really rough, he took too many chairshots to the head that year. He was already starting to lose it at home, was really angry and aggressive and violent, one night got really violent, nearly murded Julie in front of the kids. He was strangling her with the kids crying and pleading him to stop and he finally relented probably just a couple of seconds before it would have been too late. Basically he was about to be Benoit before Benoit. If he had kept going, he would have been. As bitter as he probably is about the Goldberg kick, that moment was a blessing in disguise for him, as it forced him to retire before he went full Benoit. Yeah Julie divorced him, but she's still alive, he's still alive, the kids are grown up and fine, no one went to prison for murder, and his brain seems to be ok, it didn't degenerate into full swiss cheese, seems to have recovered from the wrestling days. Yeah he's obviously not as quick witted as he was 20 years ago but he is old now, his brain seems to be at an ok pace for his age. And he's got some chocolate sugar to enjoy until he dies, to the degree that his dick will allow.
I can understand him being bitter to the end about Shawn, Gaytch, Hogan and Vince. But I think he is too harsh on Goldberg (and I don't even like Goldjew at all, was never a fan.
