Politeness has nothing to do with morality.

Mediating language about a powerful dead person to be respectful, when their life was built upon fundamental disrespect for the lives of others, is bullshit done not out of kindness for the dead but to make the powerful dead person signify nothing uncomfortable.

Because if it meant something that powerful people can be this way, can get away with things, can be praised and admired in a way that shows an infinite regress of conditional statements appended to those hard-coded values and morals that justify power, can fail and get a do-over even when that failure has a body count…

…then that power is not moral and cannot be justified by pointing to a document or pledge; but also that that power is not utilitarian in the way that it presents itself to be, but instead performs some other kind of utility that is simply left unsaid.
