I believe the correct answer is: Ogilvy’s curiosity tends to overcome his better judgment.
From these passages from “The War of the Worlds”, the reader may learn that Ogilvy’s curiosity tends to overcome his better judgment.
The indications to that conclusion are the presented danger he was facing, danger so big that brought his heart into his mouth (but he continued to go down into the pit to see the Thing more clearly) and the fact that he narrator uses the word “scarcely” when describing his sense of judgment, meaning that Ogilvy barely realized the danger he is in.
