Just like oil and water, good and bad don't mix well. That is why when the leader is bad, most of the people already expect that the team members are also bad since the good members won't last or stay good for long. They either get detached from the team or get influenced by the majority and then turn into something bad as well. The same goes for the teams that have good leaders. Which is why we always need to be mindful of the people we surround ourselves with because we can only end up getting isolated or getting influenced if we choose the wrong company.
