What a **** move. <----Tango Whiskey Alpha Tango>
First his FO bad mouths him to the cabin crew and now his 'colleague' vilifies him on pprune.
He made a decision, everybody lived. Yes, he regrets it in hindsight and no, he wouldn't make the same decision if presented with the same scenario again.
He's not one of the 'spikey hair' brigade, doesn't behave in the manner you seem so keen to attribute to them and happens to be one hell of a nice guy. He just happened to have been born in HK and there lies YOUR problem.
Get out of this company, you're not welcome here. Go directly to jail, do not pass Go!, do not collect your gratuity.
