Villainy is a matter of perspective. Loki vacillates between hero and villain, often finding himself as the frenemy of the more cut and dry superheroes. Even though Thanos advocated genocide on a universal scale, he did so because he truly believed it was for the greater good. In Winston Duke’s estimation, it was Thanos’ conviction in his beliefs, not the Infinity Stones, that made him such a threat. It’s a great point from the M’Baku actor.
