This isnt a thing because of religion and capitalism. Religion isnt really relevant for most people nowadays. And since capitalism is using more automation and creates increased inequality, humans are transforming from an asset(potential unit of production) to a liability(potential for rioting).
I think we will see a sharp increase to the normalization of ending someone’s life in the next few years/decades. And i am ok with that but it is important to realize that one of the main factors behind this change will be that we are a liability for an endgame capitalism, heavily automated world.
