Viv turning away from the dark side?...
Nope, he is an opportunist, like fox following a tiger or lion so that he can be feared and respected. If you put him alone, he will give out smelly fart to wriggle out of the situation. Even his own MIW don't really trust him and so is LHL. LKY even mentioned that this viv tried to bad-mouthed gay people to him but LKY is not wavered by such gossip and his name was not worth mentioning after that.
