Agree, the rapist analogy is absurd.
I know Parello vouched for the guy and im sure it put Merlino in an awkward position. It would of been hard to say no to Porello. Im sure Merlino wasnt too happy or maybe he was due to a big shot like Porello partnering with him.
Merlino should of kept him at a distance. Either way, he was in a bad position.
