I had never heard of Keith until now, but I am terribly sorry that he felt driven to end his life.
The media glorifies suicide and promotes it. If a celebrity, someone who has the star power and fortune is willing, then why shouldn't I, someone who is without the star power and fortune not do it? Following the announcement and news of a celebrity's suicide, people think about it more, and if sufficiently vulnerable, they may see it as a viable way out of whatever their current circumstances are. If someone is already having dark thoughts, and then suicide is in the media, it's really hard for people who are having dark thoughts to avoid doing the same thing. Media coverage of suicide causes a ripple effect. How many of us have thought about suicide in some way or form following the discovery that a celebrity we knew of did it? I know I'm guilty of that.
I think the media are doing the public a serious disservice in covering celebrity suicide. I'm not convinced that it helps to dissolve the stigma related to suicide, but rather that it only encourages suicide. "You're free now." "Rest in peace." These words (for example) suggest that we can only be free and rest peacefully once our lives in over, and I think that it reprehensible when many of our lives can be shifted for the better and we can be free and experience peace while still alive.
We have a crisis of meaning, where so many people don't know have a purpose or meaning to live for, and the media does not encourage us to find a purpose and meaning to live--but rather, they encourage us to look for ways we are being oppressed and victimized. This is incredibly unproductive and unhealthy for us.
Having said all of that, I hope that the loved ones that Keith left behind can use this tragedy as a catalyst to find meaning and purpose, and that this won't cause them to be in so dark a place that they follow the same path as he did.
