In group

Explanation:

In group is a group as the name indicated in which all people are identified to each other based on many factors such as gender, ethnicity, race, etc. People do not try to harm people who are in the group.

They would harm out-group people. People make some moral judgments based on in-group morality. When someone makes a misbehave, the behavior is dismissed naturally because they think its natural and not a big deal. But on the other hand, if someone who is out of the group does the same thing have harshly treated.
