Because Silva was wronged by M. So who do you think was the real villain?
M
Exactly. In what way did she wrong him?
She sold off his home
How did she sell off his home? Yes I know he was wronged but it's been a while since I saw the movie
After M ordered Moneypenny to take the shot, despite her saying the aim is on Bond, while Bond was in recovery, she sold off his house because there was no next of kin
Took half his screen time. In a "James Bond" film...
It's grey not black and white which is one of the reasons why it's such a good film.
