wizard_of_gore Trivia: The heavyset man speaking at the architects' meeting - the first one we see in this scene and who viewers might at first think is the adult Ben Hanscom, before realizing Ben is skyping in to the meeting - is Brandon Crane, the actor who played the young Ben Hanscom in the 1990 TV miniseries version of IT.
AerinahTrivia: Pennywise appears for only 10 minutes in the entire film.
Answer: It's a bit involved, but the fact is that he was never that stable with the idea to begin with. He had forgotten all the horrors of his childhood (either due to the influence of Maturin the turtle [from the book] or Pennywise it makes little difference) and when it all started to come back to him, he panicked. And frankly, he had no way of knowing whether Pennywise could get him where he was or not. He didn't know enough to know one way or the other. But he knew that where Pennywise was concerned it would never be over simply. Pennywise would have tormented and tortured them like he did when they were kids, and when faced with that prospect he decided that ending it now, especially in his panicked state, was preferable to the idea of torture.
