One aspect of Shaitan is that although he is evil—he is successful. He has found a way to successfully subvert the vast majority of humanity—whether they be pious or not—into sinning. This much can be said—if one can become so successful in misguiding people so successfully, than surely one can be as successful in guiding people. It only follows to reason this as good is far more attractive than evil. Shaitaan can even manipulate the feelings of righteousness to allow sins to occur. And so likewise, one can manipulate feelings of evil to allow good deeds to surface.
The other aspect that one must consider is that the success rate that shaitaan has should be able to be matched by those who are good—if not bettered.
Imagine a world where Dawah is so successful–that it can be done instantly and powerfully in the hundreds. Almost similar to a factory not made to manufacture goods–but Good. It must be possible. And He guides whomever He wills–but are we not here to guide as well?
