One thing extremely important to know about Vikings was that they were most of the time not as violent as people think, and when they were violent it was for good reasons. And they had a very strong system of morals and laws that was even stronger than the cristians at the time.
None of the vikings ever raped anybody, but most people believed a popular lie that they did. But in all of the places that vikings went to and interacted with people, those people who were there who witnessed it wrote down very clear descriptions of exactly what happened. Including if anybody got hurt or died and saying the names of all the people who got hurt, and exactly what happened to each one of them. Which usually was priests and other "important" christians. And in all of the thousands of descriptions that were written about these events, zero of them have mentioned any rape happening. And the oldest thing written that says that rape happened was more than 100 years after the vikings were gone, and it was written by a christian monk that was lying and invented the story. But other christians continued to lie and repeat each other.
Rape got the death penalty in viking society. If there ever was a rapist, he would certainly be killed. Either one of the girl's family members would instantly kill him, or there would be a trial with the whole village where everybody would know that he is guilty and would all vote for him to be killed. Women and children were always protected with the highest priority.
Also the vikings were all farmers and fishermen. Many of them even fought in the battles just using whatever farm tools they had. They survived all from farming and fishing, and trading with other people. They would trade with other villages, and trade with other countries. There were more Persian silver and gold coins found buried in viking villages than the number found in all the rest of the world and all of these were gotten from trading and selling things. They would make and sell tools, clothing, leather, fur, and anything else valuable they could find and create. And they had the highest quality steel in the whole world and it took about a thousand years for any other country to have steel that is similar quality, so they would be able to sell their swords and other tools for very high prices. There are viking steel swords that have been found all over France, Germany, and even in the Middle East that were sold in those places. And the vikings would get jewelery, fancy expensive fabrics and clothings, barrels of expensive wines from France, and many other expensive things. That they traded for and did not steal.
It was only much later that they started raiding, and most of the times all that would happen is they would go to some christian monk monastery by the water. These places were full of the most expensive golden and silver statues and other dumb things made from gold and were not protected or locked. So they would take those valuable things. And they would only harm the christians who fought them or tried to stop them, and the ones who hid and left them alone were not harmed. All of the wars that the vikings fought were not raiding or anything like that, but they were wars for farming land that was promised to them. There were English kings who agreed to sell or give land to them that they could move their families to to create farms. Then the English sent armies to the farms and killed all of the Vikings women and children. So this is what all of those wars were for, revenge for their women and children and trying to beat them so bad that they would be too afraid and not attack them again. To try to find a safe place that their women and children could be.
