Without siding with Bali, I still not seeing what the judge did was wrong. Personally, she shouldn't have gotten a "discount". Alimony is about numbers. Not actions. Financially speaking, she was responsible. Granted she gets a stay while he is in prison. Where he will serve his punishment. Once his sentence is complete, his obligation is done. Therefore punishing him further is not what the family court is about.
I don't see it that way.
Alimony is typically dependent on circumstances (and should be even in the cases where it isn't). For example, alimony is commonly terminated if the recipient remarries. The intent in most cases is a temporary transitional thing to help the recipient get their life back in order.
Now, in this case, there are two problems:
1. The recipient will be in jail - so the alimony isn't really going to be of any use in him getting his life back together.
2. Since he was guilty of a violent crime against the payer, it could be argued that he no longer has the right to expect the payer to help him get his life back together - at her expense.
I don't see alimony as something that is automatically owed to him, but rather as an equalization payment that the court can order when there is reason for the recipient to deserve it.
