the king of brobdingnag seem to redicule gulliver country during the gulliver discussion ?

The Brobdingnagian King was huge, humans were ant sized to his eyes. The king was surprised to know that "Human Grandeur" is mimicked by the small creatures. He found the norms of civilization created by the Englishmen to be "over-sized", as the little humans had created the abstract ideas of glory and vanity. The most hideous part of the conversation was when Gulliver shared the glories of war in England. Brobdingnagian King was astonished to come across such an inhuman thing of guns and wars. He found it frustrating that such diminutive creatures had designed the most cruel painting of humanity.

Further, the King was astonished at the political practices of England's Jury.The political situation was not so corrupted in Brobdingnag. The constitution was simple and just. The king did not understand what is meant by "Secrets of state" , mentioned by Gulliver. If a court case was clear it was not tampered by the Brobdingnagians further. So the King asked "wether the advocates had the liberty to plead(defend, in this case) the cases which are explicitly unjust?", i.e. in which the victim and victimizer is clear. 
This question is actually asked by Swift, It is a loophole in the clever structure of English Judiciary, The Brobdingnagian King is only his mouthpiece.
