tbf I think it is wrong to entirely remove agency from the killers themselves. It's not like even 1% of Muslims see a picture of Mohammed like that and are instantly put into a murderous frenzy, you have to be a specific level of zealous, unempathetic, and sectarian to react with violence to it. That isn't to say "the French government has done nothing wrong", but it is to say Salafi-Jihadism is an original, unique approach of philosophy and ideology that exists in its own right and not solely as a response to western governments, and the actors adhering to it are consciously doing so not some automatons reacting to stimuli like a cell or something.
