Some say that suicide is the ultimate in selfishness, and I agree. The pain and anguish it causes in the loved ones who remain is so great.
Suicide is the embodiement of selfishness, but is the right of the individual.
Just as we all have the right to life, so do we have the right to death. We all have been through wars. Internal, External it matters not. We have the scars - physical and emotional. Whether individually we chose to live or die, that fact that we acknowledge that it is Our choice.
