The difficulty is that we create protagonists we love. And we love them like our children. We want to protect them from harm, keep them safe, make sure they won’t get hurt, or not so bad. Maybe a skinned knee. Certainly not a car wreck. But the essence of fiction writing is creating a character you love and, frankly, torturing him. You are both sadist and savior. Find the thing he loves most and take it away from him. Find the thing he fears and shove him shoulder deep into it. Find the person who is absolutely worst for him and have him delivered into that character’s hands. Having him make a choice which is absolutely wrong. You’ll find the story will take on an energy of its own, like a wound-up spring, and then you’ll just have to follow it, like a fox hunt, over hill, over dale.
