Would it be fair to "lie" about the intentions of a POV character by leaving out their true reasoning? I have a character who is an assassin and he (for obvious reasons) keeps this fact a secret. In his first POV chapter, he meets someone who he is going to kill at the end of the chapter. During the first encounter, I don't explain any of his deadly indentions because I wanted the kill scene to be a surprise. There are some subtle hints that he is... slightly remorseful that he has to kill this person. But, it's his job; he has to do it, so he doesn't let it bother him too much (until later). Is this okay? Or is the reader supposed to be privy to every intimate thought of the character?
