What is the ruling on insulting and disliking Lot's wife (peace be upon him) due to her betrayal of her husband?

Lot's wife, peace be upon him, was an unbeliever, and thus she perished with her people. It is obligatory to disavow her and her actions, because her relation to the Prophet of Allah Lot did not benefit her due to her disbelief in Allah Almighty. There is no sin in reviling her by declaring her disbelief and her being cast out from the mercy of Allah.
