Yes, I think you are right. These were two very well-off people who basically had a meal ticket to success and accomplishment but chose a different path. I don't think it's because they were 'attuned' to suffering moreso than anyone (it doesn't take a genius to realize the world is a horrible, cruel place) but rather their immense mental faculties took up so much of their mind's resources that their well-being and emotional intellect suffered. At least, that's what it seemed to me but we will never know. Neither left a note.
