The point you mentioned is clear within all the literature we look at, but we also see it evidenced through our data at the centre. I'm not completely sure why that exactly happens. I think there are a few factors. One is that violence is a learned behaviour. When you see violence, it becomes ingrained in your own way of interacting with other people.
The other thing we need to look at is brain trauma and attachments at a very early age. Those things impact all of your relationships moving forward. If they are not created in a secure manner as a child, they need to be addressed, or else you will see impacts of insecure attachments and then violence in the future.
