As a non-believer, I am aware of the parable of the Good Samaritan. it is probably the core expression of the difference between the new religion and the old. It commands people to love their neighbours as they love themselves. This is an admirable instruction, But Jesus prefaces this commandment with a prior commandment - to love God. I suspect, LR, that the people you refer to are just making sure that everyone else sees that they are behaving "properly".
