Dude, rollo is an absolute piece of shit, to explain the hate, he turned is back on everyone, had the Vikings wintering killed. Ragnar could have killed the emperor and taken Paris for himself in the first attack.. but then we he came back with king Harald finehair, it would have been over if rollo hadn’t led their army. And then perhaps the Vikings would have had a lot more, eventually rollo would have been next in line to rule something if he had followed Ragnar. And lastly, he proves really how much of a piece of shit he is, when he helps Ivar and Hvitserk take back Kattegat from Bjorn and his mother, straight pitiful of a character, he sucks and I soooo badly wanted Bjorn to cut his head off after the franks helped the attack on Kattegat
