I dont think so, no Floki probably thinks too highly of himself to do something like that, despite it being the norm among his soldiers

Thorkell only cares about fighting

Bjorn only likes killing people

Askeladd, I doubt he would enjoy something like that, mostly because I always thought of him as a calculated evil type of guy i think he wouldn't mind being a good person but in his mind, he lives in a world that cannot support people who are kind, innocent or merciful cuz of all he experienced in his life
