Jack's Personality:
Jack is very much an (undead) gentleman, graceful and patient in equal measures and can usually be counted on to do what is in everyone's best interest.
Though his logic is sound. his reasoning can be questioned at times--he was quite thorough in his Christmas research, but opted to go with what he and his friends knew when he decided to give Santa Claus the year off and take over for him. He was also oblivious to Sally's feelings for him throughout most of the story, showing that while among the more intelligent citizens of Halloween Town, he is a bit of a dope at reading people's feelings. This is backed up by the fact that he barely even recognized Santa's distress when they first met. It seems that Jack might be slightly naive at times, as shown that he trusted Lock, Shock and Barrel enough that he believed that they would simply bring Santa Claus to him without causing trouble, despite them being in cahoots with Oogie Boogie. And he didn't realize all the chaos he was causing on Christmas Eve before it was too late. Jack almost never loses his temper and hardly ever raises his voice, but Jack was unable to contain his contempt for Oogie Boogie and did not hesitate to severely punish his old foe for endangering his friends with grim dedication. It is also shown that Jack enjoys things that are new to him. He quickly became delighted with Christmas and grew increasingly excited as Christmas was being remade in Halloween Town just as he pictured, even giddily laughing as he gave out presents on Christmas Eve. He is also highly optimistic, as he is very certain everything will go perfectly...that is, until he realizes how "Everything has gone all wrong." Even when in despair after ruining Christmas, he is able to cheer himself up by realizing he didn't mean to do what he did and that "nobody really understood." He is also humble enough to admit that he has failed and is willing to hand back the reins to Santa Claus in order to rectify everything
