His aspirations to become a great hero makes him somewhat of a moral sheriff in the Land of Ooo, as he is willing to help and protect any innocent person or creature. Finn has a very strong sense of responsibility and becomes upset when he is unable to help others. Finn is also almost incapable of doing anything evil or unjust, and will struggle greatly against doing such things.
