I suppose whether you view the Ishgardian Hunt as a necessary conservation act or purely as sport, the adventurers are essentially admitted into a 'gentle person's club' where they work for private scrip. Not state-sanctioned per se in the manner of the GC Hunts, but the mechanics are much the same. I imagine that many citizens would feel that, ethically, these activities are a program of lesser evil, though they may feel the contract killing of sentient but wicked beings nonetheless morally objectionable.
Interesting topic for consideration.
