(Gif set) He's terrifying and heartbreaking during this part. But you know what I just noticed? Look at his eyes - they are not really angry. He's still watching Odin - he's still sad - he still wants to be loved.
Loki and Thor...it always bothered me that while Loki mentioned his love for Thor twice, no one ever said "I love you" to Loki, when he most needed to hear it. Odin said "You are my son, I wanted to only protect you from the truth." rather than "You are my son and I love you."
