human of the year

When I was a kid
I thought bad person are those people who killed someone or steal things
After working at this new job for almost a year now
I realized that a bad person can be those
who had really bad heart/ mind
they don't care about the others
so selfish, so irresponsible
if these people work in the workforce for, let's say, 30 years?
I wonder how many people would be upset by them
To me now
these people are as bad as criminals.
