I DON'T MIND KILLING MY AUNT'S HUSBAND

Please PREVAILED BLOG,help me post this.

 I have an aunt whom I love so dearly, she has A man which she had 2kids for but the man has not Done any rightful thing on her as husband, my Aunt is very rich before meeting this reckless Man, since when they started courtship things started going Down for my Aunt, a prophetic ministry came in my church and said my Aunt should nOt marry the man but then she was pregnant for the Man, the most worst part is that the man will never support my aunt in anything she wanted to do, now my Aunt is broke to the extent that she go about borrowing money from a mortgage bank. The Man always beat my aunt anytime they have little quarrel and even if I go to there house the way he talked to my Aunt really annoys me, because of this man.
My aunt Sold two of her land and give this man the money, to cut the story short we the Family Decided that my Aunt will leave the man which she did but the man came begging for my Aunt to return Back... Since this Issue have never said anything cos I was wondering that if I should interfere in the issue I don't mind killing that man cos I don't like his Attitude,  I need ur advice, should my Aunt Go back to that Useless Man? Or just move on with her Life, I need Advice. Thanks
