[It Novel] If It can be beaten by will-power/imagination, why did It still manage to kill Eddie Corcoran?

Even in eddies last moments he was feeling for a zipper on It's back. Considering that the other Eddie burns It by claiming his inhaler is battery acid, shouldn't there actually have been a zipper that Eddie C. could have grabbed?

The book is partly about how you lose some sort of magic when you grow up; adults are too grounded in (what they think is) reality. Eddie was too convinced that what he was seeing was real and didn't have the "magic" anymore.
