This is sound.
A couple of years ago I lost my entire context: job, church, friends, FOH and bass gig, marriage, hometown. I mean, it's GONE. And no, I didn't do anything to p anybody off. I got blacklisted hard. I don't know exactly what happened, because the people who put this process in motion never said.
But guess what? My life is a referendum on MY behavior, not theirs. And while it might be temporarily satisfying to 'win' in some big way so I can say 'f you' to everybody in my former life, that's not happening and it may not ever happen. On the flip side is what you're talking about - what if I died? - and wondering what their reactions would be.
Neither course is worthwhile. Framing anything in the context of a former life, with intent of getting some sort of reaction or even wondering what a reaction might be, is neither healthy nor productive. My life is mine to live, to do the best with I can. I get to own my attitudes, my reactions, and nobody else's. If someone is happy when I die, then that's the emotion that they have. Should they be happy? Not in my opinion, but people are entitled to their own emotions. Trying to figure them out - or play to them - won't be healthy for me.
Here's a quote from Jonathan Martin: 'The only way to lose yourself forever is to keep hanging on to the life you had before.' Good words.
