Thank you for pointing and refining the writing and let me get close to the theme of the question.
“Say you were formerly a professional, would it be more of a gray area, would it be immoral not to act knowing you can save him? It would still be illegal to help wouldn't it?”
Applying the medical professional idea to my daily job, a pen company, we always mention the pen is an environmental friendly and CO2 reduced products for good company image, and moral satisfaction for consumers. Unfortunately, the painting, the coating and chemistry help the product to last longer, is giving Mother Nature very hard time to digest. It is a legal product with FDA certification, but it is immoral to the nature environment and results collateral damage to human being, which as result people won't spend time to talk about on news or social media. It is immoral to use the pen, but it is also legal. As result, if we want to have goodness for our world, we should avoid being immoral, but and not letting legal to affect the own morality. ( wow this sounds crazy)

There is goodness in everyone, and people only need a good chance to show. When hearing people gasp and startle for accident, people do care and do share their sympathy. Therefore, it is more important being legal than being immoral to protect the goodness of people from getting crushed by wrong accusation or in bad means.
You can walk up an injured personnel, try your best to save him/he and to the side road, but by doing so, you may break the law due to your unprofessional emergency action, which potentially cause extra injuries. It would be more important to have strong legal logics to set up stop sign before the accident scene to stop the coming car from having further incidents. It is only crushing my mind when seeing people show good deeds get punished. Being more legal oriental help, would protect and defense for those who intend to act for the goodness.
