Every character in MCU has different powers and traits. All are explicitly illustrated throughout each episode. As a result, the audience could understand and start to love them more easily. For instance, Tony Stark was pretty arrogant and cocky, but he is more responsible and compassionate time by time.But there is a totally different character from others and is also my favorite one, Loki. In every single movie, he appears as a cunny and crafty and never can gain the trust of others, except for his sympathy brother - Thor. Although he died In Avengers: Infinity War because of tricking Thanos to save his brother, we still can’t forget the times when he did things giving rise to terrible consequences. As such, we will bring you 8 times when Loki is truly a sinner.8. Let Forst Giants To Asgard
