Emiya may or may not have been called a hero, but he said he suceeded in his wish to become a hero of justice by staying true to his ideals, but when he made that agreement he was made a counter gaurdian instead of heroic spirit and grew to feel that  his ideals were a hypocrisy. Regardless of being called a hero, he claimed that goal was accomplished and he cursed it. That's why he wanted to kill his younger self. He didn't want to become a hero if it meant having to live a hell of perpetual hypocrisy.

And even though the Assassin are wraith, that's not far off from what I said. They are known, but not known well enough in detail, so the grail fills in the gaps. There was no real Sasaki in fate, only two individuals that were combined into a legend/fable/title that the grail had to make real in some way. As you say, it filled the roles with wraiths. It filled the roles as best it could using what it known and whatever means it has to do the rest. Like I said, at best it succeeds. At worst, it succeeds in trying.
