That's a very poor analogy - it's like saying if a cure for cancer was found and then demanding all the doctors of the world be charged with murder because "they didn't implement it until now!" Cures are not retroactive. Yes we lament that "if only that was available to us back then!", but we don't then blame them for "not having it then to save them!"

Also, tempering can't be cured because of how it works, from what I understand it works by the Primal actually overwriting a mortal's own aether with the Primal's, effectively they're replacing the mortal's soul with part of the Primal's soul. So, in a way, a tempered is sadly, already dead, their body is still alive, but their mind, their soul, their will is gone, replaced with a Primal's will. So, it's terrible, but executing a tempered is the only means available.

Sastasha HM showed clearly what happens when a tempered is over-tempered, they start to mutate into forms resembling that Primal and become literal monsters. Tempering isn't just brainwashing, it's a horrifying act that erases a person's free will and effectively their soul and replaces it with that of a Primal.

So sadly between keeping a tempered alive (who has no hope of returning to the person they once were) and thus empowering the Primal who tempered them and the result of causing more suffering, or ending that tempered's life and denying the Primal of power in order to save countless lives, executing tempered is the least abhorrent choice.
