Last Meeting 2 End It All

Would be meeting him tonight instead of 3rd Dec as he states that he would like to end it all and settle everything as soon as possible. Agreed to his request.
But somehow I have a gut feeling, it wouldn't be as civil and gentleman as I had hoped for. To think that a leopard would change its spots. Stupidity on my part.
Even before the meeting tonight, he is already revealing his nasty side to me asking me to sign some 'contract' or 'receipt' as he calls it to serve as an evidence that I am in receipt of his payment for the final divorce settlement. Yet, when I challenged him to bring it to a lawyer to get it legalized he is unwilling. Whatever...
What I want is get back what is rightfully mine and walk away from this heartless beast whom I have wasted my life for the past 12years.
After tonight, once the payment is paid, u would like nothing to do with him. He has hinted to me indirectly that if I were to get critically injured, he would be the mastermind to it. Sure. He can harm me in this lifetime but if he can get away with any criminal justice, he won't escape hell. He won't be able to escape from the punishment of hell in the after-life.
What happened to karma? Really... Why does God allow such kind of person to thread the grounds of earth and allow such kind of human to exist without karma?
Haiz...
