In the court case, in which Crofts got the GBH conviction, it was also revealed that he had taken a drug overdose. Must have felt bad about hitting his mistress so hard that her front tooth was buried in the roof of her mouth.
If CX had known about the overdose they would have had another reason not to hire him. Not only that but the Hong Kong CAD would have been interested. UK CAA must take a more relaxed view.
Crofts had no option but to keep the fight going. When his past was in the open, he knew that he had no chance of re-hire by CX.
