shadenfreude 4 beginners

i wish someone would monitor brain activity in the pleasure centres whilst a successful off-ticking is taking place. perhaps then it could be understood that humans sometimes seek to tick others off for their own satisfaction..not always for the good of the group. (though this is the mechanism by which the group IS benefited ..when the 'system' works - i.e. ticking off re not playing with fire IS valid)
it would be nice if inappropriate levels of off-ticking was as out there as 'inappropriate behaviour' as some of the ( in my view) less damaging actions thus labeled.and larnt about in school..at the very BEGINNING of education.
