Kashoggi is obviously the headline case, but far more grisly is the fact that the club has been bought to facilitate the murder of people in future. There are people in Saudi Arabia, as we speak, who are sitting on death sentences for having protested against the government and the Al Saud monarchy. Most of them are also minority shias. One young man was executed earlier this year for "crimes" committed when he was a teenager. The "crimes" being anti-government protest.
In this day and age, it would be near impossible to find a club owner who doesn't have dubious morals. It's not really possible to accumulate the kind of wealth needed, without being fairly shady. But for the most part, these people are guilty of no more than being capitalists in a society that tells itself that capitalism is the greatest thing to have happened to humanity.
Mike Ashley is a shitty person, but he is only guilty of taking advantage of the society that we have built, and made himself wealthy while others struggle. MBS is an outright killer. He will continue to kill in order to preserve his rule and the rule of the Al Sauds. Newcastle United are now a tool in those killings.
Their fans are talking about getting their club back, but eventually the smarter ones will realise that the opposite is true. They've lost their club.
