Is suicide a selfish act?

Is suicide a selfish act, in your opinion?

I see this question has been asked previously on Fluther, in 2009. Since Fluther has so many users that have signed on since 2009, there will likely be new and different answers this time.

I thought of this today when discussing the recent suicide of Mary Kennedy, who was married to one of the philandering Kennedy men. She left behind four children, ages (I believe) 11 to 17. It’s not about her specifically, but suicide in general.
