Bret Hart didn't give a good impression of Warrior in his book.
Bret Hart gave an instance where a terminally ill kid had come to see Warrior at one of the matches and was waiting with his parents in a wheelchair for hours to see him. Apparently Warrior stayed in the changing room the whole time and bitched about it when he was asked to see the kid and didn't even bother to see him even though he waited for hours.
He said Warrior was a coward and a false hero.
And also had virtually zero wrestling skills, the only good thing about him was his physique.
