Education can be something that make the violence stronger, and education can be a perpetrator. For instance, a religious school can affect the students learning because students come from different backgrounds and different religions. Sometimes, the lessons in a religious school could me very religious and focus on only one side of religion, and it can make the students with different religion feel unfair and feel like an outcast. 

Another example is that some lessons about the history could be so sensitive. The lessons could talk about bad thing of some of the ethnic groups, and it could open the way of hatred between students.

However, teachers can prevent these negative things by teaching in indirect way. Teacher should overserve the background of the students and make a lesson plan that does not harm any student, or any believes.
