I agree. Its not a very bright idea to record your sex tapes if you are sure the world will crumble upon you if they got leaked. (Again here im assuming she consented to being recorded, but it may have been a hidden camera with malicious intents). But people certainly do unimaginable things in rage and frustration. There's a netflix series about a woman who cut her boyfriend's penis in Virginia and threw it in woods while leaving him bleeding. It was a famous courst case in US

I am not saying that she is innocent, what she did is definitly brutal but we dont know if it was a simple argument. It may have been that he was black mailing the woman (most likely an ex) into continued unconsented sexual activity (read rape) or worse. In most asian societies a leaked sex tape is a social death sentence, its not exactly like a fame/money making scandal as for some westren celebrities. There have been many incidents where women or her family members have committed suicide over leaked sex tapes.
