A what if question.

[King of the North]

It is my belief that if Fengel were king of Rohan at this time he would have not gone to Gondor's aid in their moment of great strife. Theoden, being a great leader, still had to think about his decision; saying where was Gondor in our moment of trouble. If a credible and legitimate leader like Theoden had to ponder this decision, then a greedy and gluttonous leader such as Fengel would not by any means even consider helping his "ally." I believe the only way for him to be persuaded to come would be some giant reward of gold and riches. Still, this would not have convinced Fengel fully. His actions of tryanny make him seem to me like a coward.
