My favorite character

I am not sure why Jonathan decided to go to war. I don't think Jonathan realizes that he can die from being in the war. He is only 13 and 13 year olds usually don't go to war. "'Do it', he told himself 'Go and fight.'" I do not think he made the right choice. I think he is too young to enter the war. He thinks he is an adult, but he is a teenager and teenagers do not fight. This is why I am not sure why Jonathan decided to go to war. Do you think he made the right choice?
