Very good point Rai. I honestly admire actors who try not to act but to put themselves in their characters. I think Heath was that kind of actor. He didn't try to be the actor but he put himself in the character and respond or react to it accordingly.
Though, good actors should also know the line between real life or perceived real. I don't think Heath lived in a perceived real world. Sometimes, media just had to blame something or someone to sensationalize a story. It sells, unfortunately. Public sometimes buy it and it's scary, not only for the family and his daughter also for Hollywood.
