In Jordan, if a man kills a woman for reasons of "honor," his sentence may be as light as six months in prison. But if a woman murders a man for similar reasons, things are a little different.
Firas Press reports a woman in Jordan found out that her husband was planning to marry another woman and she poisoned his milk, killing him.
She is sentenced to death by hanging.
Apparently, "honor" is not a mitigating factor for women who kill. Perhaps they are considered as if they have little honor to begin with.
