>bruh talking about medieval rights like every royal line wasn't one generation away from robber Baron that went legit.
First, a robber baron isn't a baron of robbers, it's a baron who is a robber. He already is legit, he's just going overboard with his right to tax people and sometimes just outright robbing them.
Second, even if we go with the robber baron as an important criminal or whatever, that's the thing - the legitimacy of the seat and coat of arms and the crown grants you right to conduct evil within reason, and entrusts you to do so reasonably, while lacking it makes what you conduct reprehensible. It is the king's right and, far more importantly, OBLIGATION to execute criminals, but if somebody runs around doing that just because they got a longsword, they're breaking what due process there was in most medieval systems and are basically just a murderer who's targeting acceptable targets.
>Space marines can't be poisoned
That's presumptious of the nature of the medieval world, its fauna and flora, and that the poisoners wouldn't just upgrade to pouring molten lead in his ear instead of using poison.
>they are smart enough but to be trapped
Space Marines are routinely outsmarted by regular people, most often when they think they have the edge and are infallible. Space Marines routinely eat comical shit, especially due to overconfidence. They're human, fundamentally, and thus fallible.
> they have knives that can slice a knight in medieval armor cleanly in half in a single swing
Which is horrifying, and would lead to avoidance of melee by the important people, and a focus on ranged warfare against the Marine, on top of area-denial methods. A Space Marine that's stuck in a hole in the ground he did not see is a Space Marine who is not a threat.

He'd probably be able to rise to very high rank in the Empire by way of being a really big superhuman, but any sort of conquest would run into that magic would probably vaporize him eventually.
