The cells in your body, flooded with persuasive chemicals, will tell you clearly  to kick somebody’s ass.   There are many who are adept at making these chemicals flow like a waterfall.  

Your soul will thank you if you unclench your fist, make your hand soft, and do something productive, instead of kicking the ass of someone who is begging for, and richly deserves, an ass-whuppin’.  

Best to avoid these types altogether, if you can.  If you can’t, practice effective action to neutralize them.  They can sometimes actually be made to disappear, depending on your level of skill.  

Practice.
