Victor Parks [Brotherhood of justice, 1986]

The eponymous "Brotherhood of Justice" begins as an attempt by several students to end vandalism and drug sales in and near their high school, but this "solution" gradually becomes worse than the original problem. As the Brotherhood's targets expand to include all who irritate them for any reason, the group's actions escalate to arson and attempted murder. Its original main organizer, Derek, realizing what the group has become, eventually reports his comrades.

Despite being described as taciturn and a nerd, Victor doesn't seem overly insecure and can even stand up for himself. He studies well and works part-time in a restaurant, looks after himself, but does not get close to anyone. Overall, he's a very nice guy who doesn't seem to mind talking to other people himself, but he never provokes them, preferring to go with the flow.
