I mean, it’s usually used to undermine a cause by killing their leaders, but their death can also cause them to become a martyr and get even more support. Which is generally true for the majority of assassinations?
Why I asked? Because recent events in Ecuador got me wondering.
Usually such an assassination hurts a lot, and it also hurts their cause a lot.
In rare cases, a kinda martyr effect happens, then it helps their cause. But there are preconditions: the cause must be well known, and it needs many supporters already. One (or some) of them must be able to take a new leadership position. And they must be able to withstand the fear of more assassinations.
