I hate to break it to all of you, but if everyone* thinks you’re a good person, you’re probably a good person.
*in b4 someone names a famously charitable monster: everyone didn’t think Jimmy Saville or Bill Cosby, for example, were good people, to be clear. There were quite a lot of victims who thought otherwise. Also they were much more concerned with whether people perceived them to be good people than whether they were good people, so you’re also clear on that point if you identify with this.
