The point of view expressed here somewhat ironically show a severe lack of humanity. If anything it seems more humanity is needed here.
It’s not uncommon to hear people talk about various types of population control/reduction while being seemingly oblivious to just how tragic and psychopathic the point of view is.
If you find yourself agreeing with, say, Thanos, and also think it’d be great to see half the world’s population reduced by half, I think that’s a pretty strong signal that you need to really think about what you’re saying and if something can be done to increase your ability to empathize with people in need.
Another approach, that doesn’t involve letting people die, directly or indirectly, through our (lack of) action, would be to address issues that cause long term high population growth, in addition to for instance developing technologies and making cultural/lifestyle changes to accommodate more people on our planet to the extent that’s needed.
