People who sin or do something that they know they shouldn’t do often encourage others to join in with them. Somehow this makes it more okay. Have you ever done that? Did something you knew was really wrong but did it when you saw others doing it?
Have you encouraged others to join in with you in doing something you really knew was wrong because it encouraged you to do it and somehow made it seem more right than if you did it all by yourself?
Gang violence is like that. People who wouldn’t ordinarily destroy property, curse, pick on other people are more likely to do this when they can get others to join them in doing it or they can join a group that is already doing this and they feel there is safety in numbers.
Bravery occurs when a person does something all by himself or herself without the support of others or the example of others doing it.
