In the UK 'the decent thing' is to commit suicide. Lucky lord Lucien was supposed to do this after mistakenly killing the nanny he mistook for his wife.
One of my ancestors waited for the laird to do the decent thng. The laird thought it great fun to strip a young female tenant, have her flee in front of the male guests assembled for a fox hunt and gave her to the winner.
When he got tired of waiting, that Kavanaugh shot the laird, his 3 male heirs, wiping out the family lineage and burned the manor to the ground.Then he became an artilllaryman in the Austro-Hungarian army, the american army, the mexican as a san Patricio Gringo and then moved to California, where we keep our firearms cleaned and oiled.
Lets have no more talk of social decency.
