The more high profile a person is, the more expensive it is to take out a contract on them. We know that killing an emperor (even in a time that the empire's power has waned considerably) is prohibitively expensive, well out of the range of the average person.
The dark brotherhood also does not take conflicting contracts, which would prevent such "vicious cycles".
We've also been given reason to believe that if an assassination is foiled, and the assassin killed (for low profile contracts at least) then a second attempt will not be made (unless they are paid again). This is of course unconfirmed, but the events in skyrim (assassin sent after the Dragonborn, without a second attempt for the same crime) seem to imply this conclusion.
Not to mention that the Black Sacrament is somewhat unpleasant, and extremely suspicious to acquire the materials for. That would deter many people.

But from a business perspective with a contract involved. Its important to keep sending assassins until the contract is fulfilled. Its very bad business for an assassin organization to not hit their mark. If other potential clients get wind of your organization failing to accomplish what it promised to do after taking money from a client. Theyre going to look elsewhere for their needs. That trust and expected reliability will be lost.

Would be pretty natural that summoning the dark brotherhood is illegal, hire an hitman is and has always been illegal.WhiteCoatSyndrome wrote: »Let's not forget: in Oblivion at least, summoning the Dark Brotherhood is illegal - that's how one of the NPCs in the prison ended up there. It's reasonable to assume that other major governments had similar laws, so their lawmakers wouldn't get targeted. So if you keep summoning them, sooner or later the guards will notice and arrest you.
Also, the more important/powerful someone is the more likely they are to have bodyguards in their employ, and people with a lot of personal power in the non-political sense (exceptional fighter, powerful mage) are probably hard to take down. The Brotherhood doesn't have an unlimited number of assassins, getting one that is qualified to do the job into place may be very time consuming for targeting (EX: ) the Emperor - witness Skyrim.
