In vampire diares we saw about hunter's curse in season 4 and season 5.
When a vampire kills a hunter from a brother hood of the five (even the said vampire is a original or a hybrid ) causes the vampires to be psychologically
tortured by the specific hunter after death by creating powerful hallucinations, slowly bringing them to a madness that coaxes them into taking their own life.
When Alaric saltzman killed a hunter who is torturing damon salvatore, why
Did'nt alaric was psychologically tortured because of the hunter's curse?.
