Vikings is definitely one of those shows where every character is always at risk of dying, many episodes include giant battles and massacres! So if you like shows that will have you on the edge of your seat for every episode than make sure you go give Vikings a try! It is a VERY mature show, there is a lot of violence and gore as well as sex and nudity so you should read the parental guide on iMDb before letting kids or even teens watch it. I normally think ratings are too strict but on this show I really think it should be TV-MA.
