Journeyman - “… these days most of the cases they try to bring are at best dubious and at worst vexatious…”
I think over the years, they’d come to buy into their own hype that their past court victories were evidence of God’s favor (as opposed to careful planning by shrewd lawyers).
Believing that they’re “destined to prevail no matter what” would definitely tempt them to pick more and more fights they wouldn’t otherwise win.
In fact, I suspect the possibility of losing is almost foreign to them.
