Nah, I think Loki's death scene was pretty powerful enough for a couple of reasons. 1. It's witnessed by Thor, silenced and totally powerless to even attempt to stop it. And then, a lil while later, it's even showcased by Thor stating as such when talking to Rocket about his losses. I think that scene was actually very well done. It was subtle, yet powerful, as you see that Rocket is contemplating on just what they're up against before consulting with Thor and when Thor tells him about losing pretty much everything, very recently and Loki at that, what he's saying and yet emoting, the struggle of keeping his shyt together and using it to motivate him. He let a tear drop, whilst simultaneously very slightly smiles, trying to not only convince Rocket, but also himself. It's actually one of Hemsworth's best acting moments throughout his role with the character tbh. I mean that in a positive sense. No sarcasm.
