IF Jax Adopts Morgan

why do people think that is the solution to the kids(Morgan) being out of harms way. By now i think Sonny enemies know about Sonny kids. So why have Jax adopt him(besides the reason that it would tick sonny off) IT is not like Sonny enemies are going to be like "no don't go after him he is not a corthinos anymore" They still knoe he is Sonny kid. Other than Sonny and Jax being at each other throats again i do not see why they are acting like teh adoption would protect Morgan
