I assume all of us have evidence of this in our daily lives.
Even the best people we know have bad days. But you have probably also encountered people in your life who have consistent patterns of being selfish, destructive, toxic, or harmful.

This is not evidence that most bad acts are done by bad people. This is evidence that I've met people who've annoyed or harmed me at one or more points, and projected my personal annoyance into my fantasies of their internal states or of their essence. Their "badness" could literally have only consisted of the things that bothered me, and during the remaining 80% of the time (that I wasn't concerned with) they were tutoring orphans in math.
Somebody who is "bad" 100% of the time on twitter could be bad 0% of the time off twitter, and vice-versa. Other people's personalities aren't reactions to our values and feelings; they're as complex as you are.
As the OP says: our definitions of "badness" in this context are of commercial badness. Are they annoying our profitable users?
edit: and to add a bit - if you have a diverse userbase, you should expect them to annoy each other at a pretty high rate with absolutely no malice.
