As far as criticism goes, it takes some creative effort to get much harsher than that. It is far beyond constructive criticism; the target is asserted to be far past salvaging so the only good thing that could happen to them is a bad death.
I guess maybe you think it isn't criticism at all because it's not constructive criticism. But it's certainly criticism, no reasonable person could construe it as anything less than critical. And because it falls short of a specific and imminent threat, it's legal political speech.
