What I satisfy myself is: "People are responsible for their own actions". That relies on some emotionally intuitive notion of "responsible" which I cannot bootstrap from what I know of the universe. That is why "free will" is foma to me. Rationally I do not believe it to exist because I cannot define it rationally (not only do I find myself unable to do it, I believe that it is not possible).
