Vaidya has no qualms with killing the undead with positive energy. The undead to her are not the "vile abomination" as other healers would say. The undead are merely husks without souls. They may look like loved ones, but they are not what people knew. Even the intelligent undead who have the memories are merely husks with memories. For they all have one thing in common, they lack the spirit they are born with.
Living creatures on the other hand she doesn't want to harm them, much less kill them. Even if the living enemy in question is trying to kill her, she will not try to kill.
She believes that it is simply not her place to cast judgment upon the guilty or to take the life of another. For there are people whose place it is to do such things.
It is the executioner's place to kill the guilty. It is the judge's place to deem who is guilty and who is innocent of the crimes. It is the farmer's job feed those around him by raising the livestock and grow the crops.
Her place is to be the healer of the sick and wounded. Her place is also to pass down the stories of her people and the traditions they held. Her place is to understand the oddities in the world and inform those around her.
The way she sees it, killing the living when it is not her place to do so is to anger the very Loa aka Spirits. Not that the skies would darken and a fireball comes from the sky to smite her for being wicked. The Loa would display their anger through nature itself. Like a panther attacking her in the dead of night when normally the panther wouldn't have come close to her and her entourage to begin with and would normally have sought easier pray.
She is not afraid of dying as she was taught her spirit will become one with the land again.
Even though she acknowledges herself as a pacifist, she does not consider herself a coward; she sees herself as brave. A coward would stay in their comfort zone and let the pleas and cries of the sick and wounded fall on deaf ears for the coward would consider it not their problem.
