ELI5: Could a country legalize murder?
gpt
You couldn't legalize murder in a pedantic sense, because murder is by definition an illegal act.

But you could "legalize" killing people, and most countries already do in some sense. It is legal to kill people in self defense or the defense of others. It's legal to kill people during war. It's legal to kill people as penalty or breaking the laws. 

So the question is, can a country make the definition of legal killing so wide as to effectively make everything an excuse to kill someone... And the answer is yes.
