Both had shortcomings and both maintained this friendship, Karna died fighting for him after all
Definitely not made his friend seeing the capability. He was a student along with others, neither Drona nor anyone else has ever mentioned that he was better than rest, Dury was a kid, he can no way realize Karna's true potential.
Multiple instances show Duryodhan didn't have a conditional friendship
Plus it wasn't like Duryodhan made him his servant
