My opinion won't make you care more or less about the individual, but. . .
"It couldn't have happened to a better person"
It happens to all of us, good or bad.
I offer this though. During a particularly bad breakup I was given a book of short poems on loss and grief and this one liner stuck with me.
"For anyone who has ever wished me ill. . .today, you got your wish"
I never gain in being gladdened by someone else's loss or pain.
But neither are we built to personally feel the death of those we don't care for.
We have to learn to do that. One of the things I think we were made to do.
Just my opinion
