You seem to imply that someone who tries his fullest to learn will have lesser middos and religious maturity than someone is better able to learn. I totally disagree.
You are oversimplifying my position. There’s obviously more to it than that; you can find two people equal in both, yet one can be greater than the other.
However, don’t deny the ability of the Torah which one has learned to make changes in a person. I reiterate: ein am ha’aretz chassid.
