Freedom of *thing*

I was shocked by some of the statement made on Charlie Hebdo shootings. They opined that such a comic that poked fun at religion will have such a consequences. 

But the fact is, such is not the case of tit for tat. 

The freedom of speech doesn't give the right of freedom to kill.

Similarly, would it be acceptable that when someone was killed, the killer is only subjected to rebuke and satire comics thrown on him/her?
