That’s my point. Quirrell has plans for Harry. Any worry about what Harry will do is better explained by worry that Quirrell’s plans will be thwarted by what Harry does, not by some supposed worry of Quirrell’s that Harry will destroy the world. And more likely than any worry is just the opportunity presented by Harry’s resolve to bring back Hermione by any means necessary.
