Do we have to believe that good people exists?

Is thinking that there are no good people / followers of five precepts in this world a wrong view? I read this in some where but I forgotten it. It is hard to see that kind of people other than Buddhist monks. This is a reason for some people to not to follow buddhism. Some times I feel the same way. Is this a wrong view? Do you meet real Buddhists in real life other than monks? I always try to remember that the metaphor of lotus pond. Kind regards.
