Who was 'Jack the Ripper'?

Was it:-

a) Some dude called 'Jack'?
b) Aaron Kosminski?
c) Lord Randolph Spencer Churchill?

There has been considerable speculation about when Churchill became infected with syphilis. Some report it was during encounters with London's prostitute network, others say it was just a one off encounter with a Blenheim housemaid, some during a drunken episode as a student with an old hag? The source of this latter story was journalist Frank Harris in his autobiography My Life And Loves, who was told by Louis Jennings, a friend and political colleague of Churchill's. For decades the collective Establishment have tried to spin such allegations as conspiracy theory and have often tried to bury any of Churchill's dark 'encounters'. Churchill's link with Jack the Ripper has gained a lot of traction since the proliferation of the internet According to Author Melvyn Fairclough, Churchill, being the highest freemason in the land and protecting the good name of the royal family and the position of the crown, gathered together a group, which consisted of Sir William Gull, John Netley, Frederico Albericci, and J.K Stephen, in a plan to murder five prostitutes including Mary Kelly, who had been using their knowledge of Prince Albert Victor's secret marriage to Annie Elizabeth Crook, for blackmailing purposes. This has continually been denied by the establishment and police who - especially at the highest levels - were and still are all overwhelmingly Freemasons.
While there may no longer be any documentary evidence left to prove that such a marriage ever took place, it's not impossible to assume, given the circumstances that they were having an affair, it's also important to note that In those days, there was extreme prejudice against the Irish Catholic community who were deeply despised in society even during the Irish famine of the mid 1800's, so any relationship between a Royal and a Catholic would have been incendiary.
The Establishment went out of its way to claim that Annie Crook belonged to the Church of England, and was not a Catholic.

Churchill, it has been speculated, resembled George Hutchinson's extraordinarily detailed description of a man seen with Mary Kelly shortly before she was murdered. The Pall Mall Gazette June 28 1884 described Churchill as, 'Of average height with a wide turned up moustache, beautifully dressed, his gold chain has the solid appearance of real 18 carat'.
So, we have several layers of denials.
There was clearly a motive for these murders accompanied with denials. .
It's very difficult to assume how Randolph Churchill wasn't somehow involved in Freemasonry which is known for its open secret about its secrecy, protection and the ritual murder of anyone who speaks out - Could these murders be a message to others within that community to keep silent?
if so, then here is an extremely plausible and classic case of how the elites with the means, motives, power and wealth could easily abuse the poor and vulnerable into submission and exploitation.
