Question for MCU fans

MCU fans have said for years that even though Bucky killed the Starks, Bucky is innocent and shouldn't be arrested and charged with murder and have to go to trial because he was "brainwashed" and Steve did the right thing helping Bucky flee from the law.

In a recent Netflix documentary, it was reported that New England Patriots player Aaron Hernandez (who was convicted of the murder of Odin Lloyd), had a severe case of chronic traumatic encephalopathy (CTE), a brain injury associated with recurrent concussions, as well as his father’s abrupt death when he was 16. So basically Hernandez had a severe brain injury and also lost his father when he was 16.

Do MCU fans think that Aaron Hernandez should've been declared innocent and not arrested and charged with the murder of Odin Lloyd and not have to go to trial because he had a severe brain injury and he lost his father when he was 16? Do MCU fans think it would've been OK if Hernandez' best friend helped Hernandez flee from the law?
