Your points make little sense regarding human nature.

I kindly throw that ball back at you. To humor your vision of an immutable nature, it urges us more to run naked in the woods among our close relatives than to form planet-scale social structures. But again, I'll pretend it's how things are (accounting for the whole comment, not just the quoted part): the answer appears as evident as reducing the scale of our social structures, and work towards degrowth; and hey, it just so happens to be the form of communism I'm advocating for! 😛

I doubt you feel actually sorry when hearing or even seeing death to strangers

Just wanted to specifically touch on that: first, I find it detrimental to a sane analysis to assume our own vision of things as the norm, you'd be better of if able to detach yourself further, but you do you.

And second, do you need a strong emotional response to something in order to care about it? Having been emotionally numb for as long as I can remember, it's something I genuinely can't understand. Seeing things through an analytical lens as well as my values is enough, I don't need to feel outraged by something to keep in mind at long term that it should be addressed: envisioning a feminicide, a school-shooting, or a mining accident as the result of (to grossly and simplistically summarize) a lack of education, lack of proper mental care, or lacking/exploitative policies, and acting accordingly at my level seems, to use the term once again, more sane.
