Only those who have genes for exceptional physical stamina, physical nimble skill and intelligence, in other words, not many people, can be Batman. Batman is more exceptional than Captain America and Cap had a super serum to make him perfect physically. Batman is olympics level physically talented and trained as well as highly intelligent. Not many people fit that bill. At all. His super power is fate. Exceptional talent `+ exceptional recourses + victim of the worst kinds of crime – genes, inheritance and trauma. What Batman does that we can do is to make the choice not to give in to depression and do something good with our life. We can be incorruptible, like him. That is why we can all be the Batman symbolically. But hardly anyone can actually BE Batman. Such a bullshit slogan.
