Morality of catfish

At the end of the semester, we finished watching catfish. On the last day of class, we talked about how the actions of the woman is either good or bad. In my opinion, I thought what she did was immoral. She lied to the guy in the documentary about who she really is. She lied that the daughter painted but it was really the mother who painted. So pretty much, it would be immoral because of all the lying. While discussing about, some people say it is not because of how the mother made sacrifices to take care of the two sons that were handicapped. Still, it would be immoral because she lied and trick the guy to falling in love with somebody that never existed in life. So, catfish would be considered immoral because how it makes people believe that there is this person in real life that they fall in love with. To find out that in the end, the person never existed and it absolutely destroys the person who was lied to. In retrospect, it can also be good because people sometimes end up falling in love the person that was lying to them. The question is catfish moral or immoral because there many outcomes to the situation? It is up to people on what they think it is.
