It's called honor-based violence.
"Honor-based violence frequently occurs due to the desire for female purity. The practice stems from cultural ideologies that women belong to men or are a symbol of their familyââ¬â¢s honor.
Traditionally, some cultures consider men ââ¬Åguardians of female value,ââ¬Â and therefore, experience dishonor if a woman becomes worthless by destroying her virtue." Posted By Ghost
