ARROGANT is a very appropriate word to describe the wt organization.
When a group (GB) claim to be chosen and appointed by God as his earthly representative, then the attitude of that group's members will be, EVERYONE on earth, not only JWs, is accountable to them, including earthly courts of law.
While God may allow testing by fire, they fully expect they will be ultimately victorious in the highest court to display to the nations, God approves and supports them and their organization.
Of course, if when they lose, will never indicate they do not have God's support and blessing.
