No. He leaves probably one of the few things that made him genuinely happy because those were Barbara's wishes. Doubly heartwarming because until Barbara, Strickler was motivated almost entirely by self interest, but I Want My Beloved to Be Happy proves he is capable of selfless acts. Triply so because it was this that made Jim see the good in Strickler and express aloud hope for Strickler becoming a good person in the future.

In the Hall of the Gumm-Gumm King
