Who says he hasn’t murdered yet? How is this a pertinent question??
You called him an assassin, but we only have your word for it. As far as I know an assassin is someone who has killed some one. Assassins don’t have a label that says “Hi, I’m an assassin.”
It’s his moral duty to protect the life of the president and killing an agressor is not wrong if that is what is required for the aggressor to be stopped.
So many principles completely unrequired.
1-Why is it his moral duty to protect the life of the president?
2-Why is killing an “agressor” required?
3-Who/what defines what an “agressor” is?
etc…
That’s the scenario.
That’s because it isn’t real… you defined that the only way to stop him was killing him. That doesn’t make it factual.
Maybe the “assassin” is “justified” in killing the president to protect other people!
What is that supposed to mean?
It means that you are using the kind of analogy and reasoning that people use to justify what are considered “immoral” actions like abortion, premarital sex, and other stuff.
You are making blanket statements about things you obviously have not put much effort into thinking about. Your scenario is too simple.
Imagine that the “assassin” pointing the gun at the president was a little kid who didn’t even know how to take the safety off the gun…
Imagine that the security guy saw a fake weapon in the hands of somebody…
Imagine that the “assassin” he shoot at had a bomb that exploded whenever his finger was off a detonator…
Imagine that the bodyguard was having a hallucination due to drugs he had previously consumed, or medication he was on.
Imagine that the bodyguard didn’t have enough aim to shoot him in the head and instead ended shooting a pedestrian that was walking by…
Imagine that the bodyguard was protecting Kadafi… (or Staline if you prefer).
The bodyguard has to protect the president… not cause the killing of another human being/crowd because of it. The aim is in the president, not the assassin. The bodyguard could just as easily step in front of the president or push him. He could also aim for the gun or arm holding the gun (if he has that good aim to shoot him in the middle of the head).
I fail to see why it is his moral duty to kill the “assassin”. (Which you haven’t proven yet to be an “assassin” btw)
