32-year-old Zainab Bibi of Pakistan allegedly killed and cooked her husband Ahmad Abbas, and only got caught because of the tell-tale odor of rotting flesh. Police say they got involved after neighbors "detected a foul odor." Bibi and her 22-year-old nephew are suspected of stabbing Abbas to death, slicing him into pieces and cooking him.
By no means are we condoning Bibi's actions, but her motive was understandable: Abbas wanted an "inappropriate" relationship with their daughter. We can actually picture Bibi telling her husband she would kill him after his disgusting confession, and she made good on her promise.
She doesn't regret her actions either.
