emotions are important. lack of emotions is an impairment that you need to work around.
sure there are benefits of lacking emotion and there are negatives about having emotions
but emotions are there for a reason, they are signals about your state of being.
and affectionate empathy seems to give many people meaning in life and it makes the world not crumble into chaos
lacking those brings boredom, which could bring many other problems, mostly self destructive stuff
lacking all emotions will make you a lifeless robot who has no reason to do anything
lacking only some emotions destroys the system of emotions a human has, which are there for self defense, as long as they are used properly
having emotions and being able to understand them, will bring you balance, stability and joy
