Loki and surtur once joined forces and brought Ragnarok & thus the end of Asgard.
loki is the reason why ODIN DIED
then later loki ailed himself self with osborn & the result was the end of Asgard AGAIN
loki is the reason why Bor is dead right now
loki is the father of the midgard serpent Fenirs wolf , and Hela and all of them are horrible people
he has tryed to kill thor multiple times.... WHY DOES THOR TOLERATE THIS?
