I don't understand this....

This is something I've never understood about people. (Note this is just a generalization, I'm not using real people, I've just read about this).

Let's start with a group of people made up of all backgrounds, ethics, morals, you name it. Some of the people disagree with others. Fine, that is life. And you have some that get along no matter what. Until something happens. One of the people can mess up in life, be it bad decisions or what have you. Everyone still accepts that person and doesn't make a big deal out of the mishaps. Then you have the one person who has been understanding of everyone. Deep down they might not agree with everything, but they feel friendship outweighs being overt about their personal beliefs. That person makes a mistake. And it is the biggest deal in the world. And the mistake was a small one. Rather insignificant compared to the mistakes of others. Yet it is a big deal. Is it because that person has accepted everyone else and was supposed to be above making mistakes? Why can't they be as understanding and not critical as this person was when they were going through their troubled time.

This is just one of those things that's always bothered me.
