I need advice about a plot/character that's part of a bigger story. The plot in question centers around the leader of a viking style explorer expedition of around 150 people aged 15-23, of which he is the oldest. Since they are all dumb kids, they follow him blindly. He is also supposed to be inexperienced, naive and having the power go to his head, leading to a big chunk of his peeps getting mangled by natives/disease/wildlife because of his overambition and poor management. Any tips for writing this style of naive leader type character, or any book recommendations are very much appreciated.
