Sir William Gull

[Lewis C]

So nothing at all comes to mind about working on a human body uninhibited to further medical science ?

Not much imagination.

Yes, I can't imagine how any of the murders, with the possible but unlikely exception of Kelly's, could have furthered medical science, if the mutilations have nothing to do with it. Keeping in mind that he couldn't have removed the organs without mutilating, and aside from Kelly, he only spent a few minutes with the victims. If that means that I don't have much imagination, then please aid my limited imagination by telling me how the murders could have furthered medical science.

More importantly though is that what you're doing here is imagining a possible motive that Gull could have had. So even if what you're imagining is a reasonable possibility, it's the case for any suspect that they could have a motive that we don't know about. The only reason I'm talking about motive is that you brought it up. Motive is usually something I don't pay much attention to in comparing suspects in this case, because I think the probable motive is that the killer got sexual pleasure from mutilating, and there's no telling who might have that motive.

You give the Royal Conspiracy too much credit.

* A group of semi-homeless alcoholic prostitutes decide to blackmail the British government over something provably false.
* The British government decides this is a serious threat to the monarchy.
* They assign as killers a man who wasn't in England, an elderly stroke victim, and a coachman.
* The men assigned to eliminate the blackmailers decide the best way to do this is murder them in a way that turns the women from nobodies to household names, implicates the Masons, and undermines public confidence in the authorities.
* The British government agrees this is the best way to quietly and secretly eliminate the blackmailers.
* The victims fail to notice or respond when only members of their blackmail club are being messily butchered by the Ripper.
* Over a year after the doctor stops murdering and leaving clues implicating the Masons, the Conspiracy decides he is a threat to them.
* Though the doctor is well known in the medical community and pictures of him have appeared in the print, the Conspiracy decides to fake the doctor's death and put him in an asylum instead of killing him.
* The painter betrays the Conspiracy by spending the next several decades leaving clues in his paintings and hiding a child from them, but makes no attempt to flee or hide his identity.
* The Conspiracy, who have the resources of the entire British Empire, send only the lone coachman after the painter and the child.
* When after over a decade of failure, the world's most inept assassin gets run over by his own carriage, the Conspiracy does not replace him.
* The painter lives for 4 more decades, untouched by the Conspiracy.

It's total nonsense that requires everyone involved to be an inept idiot even before we consider that the source of the story admitted it was a hoax.

I was doing my best to try and be generous...
Saying "We all know the Royal Conspiracy is a steaming pile of Horse ****" would have been more accurate, but it invites the sort of distracting remarks that tend to begin "Are you saying..." and paraphrase your comment in a way that tries to discredit the position, in an attempt to ignore the substance and focus on turning the discussion away from the subject by steering the conversation toward the etymology of manure.
