The people getting roped into fighting wars will need PHDs in religious philosophy and an extra requirement of rubber brains to navigate the mental gymnastics apne churn out at times to justify certain concepts.
Just accept it's okay to want to see your enemy dead. I don't want to hug him or love him. I want his blood, not his friendship. The rest are superfluous concepts too complex for Punjabi minds that have never been adhered to in the cold harsh reality of war, and if true would get good men killed needlessly.
I agree but I don't think it's been amplified, I think what happened is that we've become aware of it's existence. Previously we'd conceptualise this type of behaviour in people in another way - like the guy's just an a-hole. Now we know that something very deeply psychological is going on. We know it can be societal. We know these people vampire off other people's energies, and are by default malicious and deceptive. We know they struggle with empathy and can do the most damaging things to people for no reason other than some power buzz they get out of it.
