I'm sure the LBD didn't help, but family members always try to claim that their loved ones weren't in control of their faculties when they committ suicide. I suppose it's what they think they ought to say to avoid shame.
I guess i'm saying that i see suicide in bad cases of degenerative diseases (with no hope of a cure, and depending on the situation) as closer to a form of euthanasia, but when you're dealing with depression (especially self diagnosed, which can mean just a mild form of it, exacerbated by a bad environment) it's a very different beast.
From what i understand of Williams' situation, he was more in the former camp, rather than the latter.
I know I wouldn't want to ride it 'till the end, if i knew my mind was going to slowly but surely erode away day by day.
