Iryna's death was an example of a failed state, letting a repeat offender go free until the next big thing has happened. Kirk's death demonstrates lack of protection for people with a different opinion. That's way more grave, a quasi totalitarian state. These kind of assassinations usually precede civil war.
at the timing of this post, we still do not know the motivations behind this assassination, you are wishing martyrdom on someone when we still yet do not have the answer.
