From Fallen London Wiki
"The even greater incentive is that you get to effectively kill that miserable fool Beechwood."
"Not to mention that you're giving up on getting the Fruit of the Tree of Knowledge of Good and Evil as well as the chance to kill Beechwood, and really, are you truly being kind in sparing him in this way? Just put him out of his misery."
the guide writer really hated beechwood lol
