I think the vikings don’t deserve their violent reputation for the following reasons….
Firstly most of the vikings were farmers so they were not doing much harm to anybody like the warriors were training to do.My next reason is that they were only there to get food to survive as their land was not safe to live off.Thirdly they were just fighting to protect themselves from the evil monks that were clearly not kind and starting the fights.Next, they never killed people much only animals so they clearly should not deserve this!
