Society cannot allow or justify murdering someone for free speech.

That's a nice soundbite.

Op implied that murder was a response to speech, and I am saying murder should not be allowed or considered as a response.

So those are two different things you have right there.

"Op implied that murder was a response to speech" , indeed he got shot because someone thought he deserved it.

"Murder should not be allowed or considered as a response"

This is where is goes off the rails a bit.

OP wasn't saying (or implying) he should have been shot for talking , just that it seems reasonable to assume he had.

"I don't care that this person is dead" isn't the same as "this person deserved to die"

If you can't see how those two things are different i can see why you're struggling.

It shouldn’t be hand waved away like “ah well what did you expect”, or fafo or whatever. It should be condemned unanimously.

Subjective but you're entitled to your opinion.

"He's dead and the world is a better place overall" is also an opinion to which people are entitled (unless you've been arguing some other kind of free speech? )

And as it seems you are having a hard time with this i'll add the explicit context:

" He's dead and the world is a better place overall ( this doesn't mean i wanted him dead, but i'm not sad that he is ) "
