I think the fact that Bury was abusive to his wife increases his chances of being the Ripper rather than lessens them.
Well statistically, it increases his chances of being a murderer. He is violent with her, and so with others.
To be a serial murderer based on violence to his wife is a different ball of wax. Usually this evolves into the fact that he hates her and symbolically kills her by selecting victims that remind him of her. THIS WILL LAST UNTIL HE GETS THE COURAGE TO MURDER HER.
Looks wise, the C5 are all over the map. This could point to a murderer whose only criteria was the victim must be female and alone. There is no evidence that Catherine Eddows was soliciting at the time of her murder,for example, she was headed home having been released from jail. As she already stated she would get "a damn fine hiding" when she did arrive home, it is doubtful she would take time out to solicit, she would be hurrying home
Just a thought
And the questions always linger, no real answer in sight
