I know that, and you know that, but IMHO Michael is still afraid.
> Michael is still afraid
I'm not well informed on the conspiracy theories accusing him of murder. However, I've seen rather a *lot* of situations vaguely like Mikes, where one spouse becomes, in essense, a massive burden to the other. Same with children and senile/otherwise disabled parents. Love can turn to bitterness with extreme stress like this.
It might not be terribly romantic, and there are certainly cases where love endures, but wanting the massively disabled spouse to "just die already" is just not that uncommon.
