I'd do the same for America, but I think you get the point
Well, yes, covert agencies engage in shady activities, under the direct orders of (typically) politically-appointed heads. My point, however is well-demonstrated in that story about MI6 supplying the Argentine navy. The totally standard interest in placing an agent within the Argentine military structure was in conflict with the law against supplying that military. In broad strokes, that's a security service judgment call. Still, the agent in question blew the whistle.
These agencies don't operate as unified, synchronized bodies. The individuals involved have their individual perspectives:
"Mr Russell became concerned that the re-equipment of the Argentine navy was going too well and that in its quest for information MI6 was defying parliament, becoming "an agency out of control".
I suspect he was protecting his own hide by blowing the whistle. That happens in conspiracies. Where are the indsider whistleblowers in the Skripal and Douma events? Nobody wants to save their own hides?
The security apparatus is an agent of capital. They take orders and follow laws because it is convenient for them. Those laws and orders are constructed by politicians and lobbyist to expand capital. If they need to break laws or go "rogue"to protect capital, they will, and they have. It would be incredibly naive to think otherwise:

William J. Casey, 1981–1987He was a co-founder of the Manhattan Institute in 1978.
And it goes on and on and on and on.
The security apparatus has an incredibly cozy relationship with capitalist institutions and agents. These are the people they take their orders from. It just happens, for the most part, that the politicians and laws are on the same side as them.
Ask yourself this: If Corbyn followed through with his promise to seize all energy assets, and requested MI6 to assist him. Do you honestly believe that they would cooperate?
You're belief that the security apparatus is a bunch of honest patriots scattered between pockets of corrupt chauvinist does not reflect reality. The apparatus has been, and will always be, a tool to protect capital. And they will do that at all costs.
