In secret, the Winter King appeared to be motivated by selfishness and/or cowardice, lacking a large part of Simon's morals. He was willing to run away from and/or dump his own problems onto others at their expense. He appeared to have no qualms with transferring his madness onto Princess Bubblegum despite the fact that this had turned her into a maniacal lunatic. It also seemed that he did not wish to remember neither Betty or Marceline, he laughs and jokes about Betty's death
