It is appointed unto man once to die. Grow old, fall ill and die... such is the fate that awaits every person.
He's already so frail and so old, taken so much money, seized so much power, written so many books, talked so much cock, planted so many trees... surely it is time to go? What's the point of recovering and delaying the inevitable?
All you LKY fans and groupies: maybe it is highly symbolic for LKY to kick the bucket in an SG50 (and possibly an election) year.
So, stop with the well wishes. People tried to pray, write well wishes, light candles etc when those planes crashed or went missing. Did those little gestures help? Humans are frail - deal with it.
If LKY were some random cardboard box collecting old man on the streets, I bet he wouldn't be holed up in the private ward with the best doctors. Save your sympathy for those who deserve it more. And I bet no mainstream media would declare that he was in a 'stable condition'.
