I think Quirrell’s ultimate goal is the Dementation of Harry, probably in order to draw out Harry’s dark side (which I think is the horcrux-fragment of Voldemort). He tried this at Hogwarts and it would have worked if not for Hermione’s intervention.
Doesn’t work. It was Quirrell (and only Quirrell) who spotted Harry’s wand next to the Dementor’s cage and alerted Flitwick so he could remove it.
If he had wanted Harry Demented he would have kept his mouth shut.
I think he did that because he didn’t want Hermione going in front of the Dementor again—she was getting too much information from it—and also because he figured (rightly) that Harry had already received enough exposure for his purposes.
