Yup. That's my biggest issue with the movie. That scene. I know it got a laugh out of people. But IMO it cheapened the villain who wasn't anything special to begin with. Ronin could have killed his ass right there.
Yeah, something Marvel has had a continual issue with... throwaway villains. Not like he was special to begin with. In the exact same movie, he's cheapening Thanos as well. When he's mocking Thanos and goading him into an attack, Thanos sits there like a punk. In one movie they managed to cut two villains at the knee.
