Jane Eyre's Cousin Needs Some Work

St. John Rivers wants to be a good parson. He wants to accomplish the heroic, to please his Commanding Officer. His quest for significance makes him a missionary candidate headed for India. He desires to wed Jane Eyre because of her skills as a "help meet" on the field. But Jane complains that "his sole desire in proposing to me is to procure a fitting fellow-laborer."
Bronte characterizes St. John with three faults:

• He does not always see the people he serves, people become means to serve what he presumes are God's ends. He does the same in his 'love' for Jane.
• He doesn't see the heroic he does do, like strolling out into a snow storm when he gets news of a dying parishioner. So the hard measure he uses on others, he also uses on himself.
• He misses the joy of Rosamond Oliver. She was a beautiful young woman. They shared a mutual attraction and her father would have been favorable to a union. But he never considers her because she is different than he is (he can't see her in India). Worse, it seems to me he can't imagine a world where duty to God and joy and contentment in life are not mutually exclusive. It may even be his 'austere Calvinism' that prevents it.

Here's the error, summarized by Jane: "He is a good and a great man; but he forgets, pitilessly, the feelings and claims of little people, in pursuing his own large views."
