Men are not robots. they are full humans.
Are you suggesting that men need to be robots to be good hunters? We have this weird obsession in our culture with thinking that emotion and logic are incompatible things. That is tragically inaccurate.
There is a line from an episode of Star Trek that I love "Emotional considerations to no impede my logic, they inform my logic." Feelings are simply messages from your subconscious, it is very unwise to suppress or ignore them.
