Will Salem not be better off without Carly?

She brought answers for Mel but all the rest is problems, dramas, violence...she has been abused but turned into somebody who is dangerous for herself and others...Bo abuses his right as a man of law in this case...how could he let her out??? he could have made the stay comfortable but not let her out!!! Who will respect somebody who does that??? He will come to realize how problematic this woman is!
