If you’re not a socio path nor a danger to society, laughing at someone, cracking jokes every once in a while.
The long and the end of it is that every story has two perspectives. Wrong and right, good and evil don’t exist and perpetuating an action that nobody can uphold 100% of their life is wrong. We’re currently holding all of these teenagers accountable for actions as if they’re adults committing war crimes.
High school doesn’t even truthfully have “bullies” in the archetypal sense of the word that you’re speaking to. There are friends, acquaintances, strangers, and people that you don’t get along with, something fundamentally true for all people. Being a victim isn’t good, healing is good. Stop creating victims and blowing things out of proportion.
