Nope, not soft-headed at all. Whatever choices you make, you have to be sure the story can continue. If you write your character into a dead-end with no way to progress, you're going to have to re-write that.
Likewise, killing off characters for no reason (especially your hero) is just a terrible idea. You get into that habit, and eventually readers will be numb to it. They won't care what trials your characters have to endure because they'll assume you're just putting them through hell for the sake of it.
