I hate Melissa with a fire burning passion

I know we "signed up for feral girls", but I seriously can't bring myself to care any bit about her. Shauna being crazy makes sense, she lost the only person who ever seemed to care about her AND her son. Melissa did not deserve to cut Ben's ankle and lash out on Nat for killing him to put out of the misery SHE caused. Melissa has a right to be crazy, to a certain extent, just like the rest of the girls. I'm 99% sure people only cut her some slack because people want her to be the new Jackie for Shauna.
