The death of Robin Williams is helping to teach people that with severe depression it isn't a "selfish act" that this person committed suicide. The fact is he dealt with a lot of mental illness, and I'm not even sure if you could say he made the decision to kill himself properly due to the severe mind altering illnesses that took control over his consciousness. Robin Williams dealt with Bipolar disease and depression, which we know today depression is attributed to chemical imbalances and not someone throwing themselves a pity party, which leads me to think of this as more so the depression being the causation of the death versus him making any rational choice in taking his life. If someone were to make the choice to commit suicide, I would now see it differently for instance someone who would choose to be a "martyr" such as suicide bombers who are being used in warfare today and terrorist actions.
An article that would be in stark contrast to my view that I'm undertaking more after this incident can be found here:
