Reb Nahman had a whole set of lessons that he said over on the statements of Raba in Bava Batra. The very first lesson of his book deals with the events that Raba said over about how he was once on a sea voyage and the sailors told him about the nature of the kind of wave that sinks ships. "They seem," they said "like a streak of white lightening at the top. But if one hits them with a stick on which the names of God are written, that causes them to calm down."
From this Reb Nahman derived the idea that the evil inclination usually does not come to a person saying to do a sin. Rather it comes saying "Let's go and do some good deed." That is the evil inclination wants to seem white and pure.
The first time I saw this idea was in the commentary of the Gra on Mishlei on the verse זבחי שלמים עלי היום שילמתי נדרי "Today I sacrificed peace offerings. I fulfilled my vows." That is: the evil inclination starts out asking one to do a good deed.
The exact details however are not clear to me--that is how to go about evaluating the situation. As a general rule, I think the best idea is that of Rav Israel Salanter--to learn the basic set of Musar books to get a clear idea of what the Torah actually requires of one--in a practical day to day sense.
