Robin Williams was a complex individual. He did many good works in his life, including helping Christopher Reeve with his medical bills. I judge a person by their overall character not a singular act, even suicide. I look at the many contributions Robin Williams made in his life and think that his suicide should not be how he is remembered.
Robin Williams had a life of good work, bringing comedy and compassion to others. His reasons for committing suicide were probably a desperate act based on his failing health and frustrations. The life's work of Robin out weighs the final act. The kind friendship that he had toward Chris Reeves was an example of his true self.
No, Robin Williams' generous acts for his friends will probably not overshadow his suicide. While both Williams and his friend Christopher Reeve were great actors, the circumstances of their deaths are what they are remembered for. Unfortunately, the public is drawn to the drama and fantastical nature of their deaths and that is what is remembered.
Robin Williams commited suicide because he lost a battle with crippling depression and anxiety. He did many great things throughout his life, and the suicide only makes up a small part of it. It is still important to remember to take care of friends and family who struggle with these diseases.
