Why didn't Galadriel warn Aragorn that Boromir wanted the Ring?

She can sense people's emotions because she can sense them, not because she needs or wants to find out about who is tainted with Sauron. And because evil that men bring with them, as Aragorn says, is not necessarily Sauron's touch. And because some of these "temptations" are not even evil, but are still temptations. If Galadriel is testing, it's not for signs of "Sauronism", but for the strength of the loyalty to the quest.
