I didn't say Melinda was justified, and really, neither of them is justified in their actions. It looks to me like they are just holding onto their bitterness because they each think that the other has wronged her, and there is no way that she is going to let that bitch come out the winner. Melinda has apologised for physically harming Jango, showing that even she has remorse, but she has yet to apologise for her actions as a whole. She essentally said "Yes, I went too far there, but I still hate your guts."
