Knowing other people isn’t that difficult.
Just look at two things.
1) the long-term result of their actions
2) their choice of companions
Chances are, someone who has displayed deep-seated moral corruption will prefer to associate with people of similarly rotten ethics or morals. They are also extremely likely to cause mayhem. I can’t believe I didn’t see this sooner!
At the end of the day, people aren’t really that complex.
