My opinion of bates has completely changed since series 4 after Vra Bates death I was convinced he hadn't murdered her.But after greenssuspicious death now I see a darker side to him he looks suspicious and if he did murder green and mrs bates it was for annas sake both times.He seems such a loyal,kind and respectable man and I love how jullien fellows has managed to change my view on his character so considerably.
Call me naive but I still do not think Bates killed either one. As for Vera, Bates came back to Downton with a scratch on his face showing he had been attacked, after all they never mentioned any marks on Vera. In anger Bates has grabbed Vera's arm and pushed Thomas and Craig up against a wall, but he has always stopped himself before he gets physical enough to hurt anyone. His mother admitted Bates has a temper and his words can be harsh but that he is not violent and never had been to Vera in spite of all she had done to him such as letting him go to prison for her. If Vera had been strangled, I would have been worried, thinking that she had finally pushed Bates to his breaking point. But even Lord Grantham had doubts that Bates would poison anyone. Bates said they had a verbal argument and suggested it got ugly so he left. Bates had a track record of just that, trying to get away from Vera. It seemed illogical that he would stay after she hits him or that she meanwhile would be baking a pie. Even more unbelievable that she would not notice that he goes to the cellar and back then dumps enough poison in the pie that she is baking to kill her. The murder scenario was just not right while the suicide for vengeance seemed like a Vera thing to do! And finally, Bates had nothing to gain but everything to lose by killing Vera. He knew he would still have Anna because offered to go away with him and to be his mistress several times. He wanted to divorce Vera and do things honorably by Anna, but he knew that if that didn't work, he still would have Anna.
As for if Bates killed Green or not, circumstance might look bad again for him, but I still do not think he did it. He may say aloud that he wants to kill Green and feel in his heart that he wants to, but he and Anna would have everything to lose if he does. Mrs. Hughes told Bates how much Anna loves him and that him going away, either leaving her as he was planning since he thought she no longer loved him (or another trial and prison) would be too much for her. Anna asked him to "brood" on her and not what had happened to her. I am hoping that is what he has been doing. Bates now knows it was Green but also sees his wife struggling to try to keep it a secret. He is not stupid, he has to have figured out that she is doing all this to try to keep him safe and with her, that he means that much to her. Bates has to be struggling too because he loves Anna and feels guilty that he did not protect her and that he, as her husband, should do something. I could be wrong, but I think Bates hired a detective in York to try to get some damaging evidence against Green. Green was an arrogant scumbag, surely there were other victims, other crimes. It has to be torture for Anna, fearful that Bates will seek revenge. But, it would also be hard on Bates who would not want Anna to know or worry that he is going after Green in another way and spending money in the process. As for the train ticket there was no date on it and it was from York to London and not Downton to London. It could be that it was an expense the detective incurred and gave it to Bates, possibly with other bills, to be reimbursed. Lastly, if Bates were to confront Green, I think it would have been face-to-face, man-to-man, and he would have wanted Green to know it was him. I do not see him tripping or pushing someone from behind, there is little honor in that and Bates lives by his code of honor, that is more something someone like O'Brien would do. Green could have simply tripped. Or perhaps he did trip while trying to get away from someone, if it was the latter, I think it was a detective or another victim. Time will hopefully tell. But, in the end, I think it will prove that in all of this, both Bates and Anna were trying to do what was always best for the other.
While I agree he most likely did NOT kill Vera, I'm pretty sure he killed Green. After all, as he says, prison was an "education" and this is about Anna's honour, and her suffering. While I don't think he is the murderer type, that is "justice" in his mind.
What do you think?
