Bucky mentally preparing himself for death is so fucking upsetting because after all of the torture he went through, after all of the physical and mental pain, he survived because Steve saved him, and here he is ready to die for him. He lets himself have this moment of fear because he knows what’s coming, he knows that he’s going to die and he allows himself to accept how scared he really is. He knew what he was getting in to when he made the choice to fight side by side with Steve (because what other choice was there really?), and part of him probably always knew this was how it would end - he was either going to live for Steve or die for him, the only thing left for him to do was to acknowledge his unhappy ending when the time came.
