Wait.....what exactly do you respect?
Killing himself obviously instead of enduring needless, pointless suffering with an inevitable end.
My Mother died of pancreatic cancer last year I wouldn't wish that on anyone or expect them to endure it, it is a horrific way to die.
Do you not consider it cowardly, regardless of the circumstances? I personally find it offensive to the friends and family.
I mean, I can't relate or find apathy in your situation, but one of my grandmothers suffered from Alzheimers for years, to the point in where she couldn't walk or remember anything, and my other grandmother suffered from ALS, and died only a year after being diagnosed, after losing all ability to move or talk. My uncle was injured in a car crash and hurt his back, and was bed ridden for two years, and died to heart issues due to being unable to exercise. All of this has happened within the past nine years.
I know they all suffered in their own different ways but as bad as I feel for their suffering and their deaths I would have been severely more depressed and disappointed if any one of them would have taken their own lives instead.
