All people are to some extent or other trustworthy. We trust people to keep their word or show up at work or to respect a confidence-- most of the time. It would be very difficult for social life to proceed if this were not the case. We would find ourselves in some feral case of society, a Hobbesian world where all doors had to be locked, people always asked to show their credentials, people always looking over their shoulders, unless there were an all pervasive state to look to the enforcement of what are generally considered normal states of freedom or lack of fear. And all people are also sometimes or other untrustworthy in that they lapse in picking up things at the store, can be unfaithful to their spouses, and in many different ways shade the truth to leave an impression that does not square with the truth.
