This was a tragedy, but millions of other families died in similar ways, murdered by the commies.
And Nicholas and Alexandra arguably deserved their fates, though their children and servants of course did not.
Most of the other millions who died did absolutely nothing to deserve it.
It is an oddity of history that the generally most decent and well-meaning monarchs in their respective dynasties were often the ones who got it in the neck during revolutions. Charles I (somewhat of an outlier in the decency criteria, though), Louis XVI and Nicholas II.
Why?
