did costello want billy to live a normal life?
you know, there was a scene at the restaurant where billy and costello were having conversation about jacky costigan and billy's father.
there, costello told billy that billy's father would kill costello if he saw them together, implying billy's father was a law abiding citizen and billy's involvement with mob business is not something his father would consider ideal.
and then costello says " did you ever think about going back to school?"
to me it felt like costello wanted billy to get out of this mob business and carry on with normal life.
well. some says costello only said that so that he can use billy costigan as spy among the cops, or use as a lawyer.
I don't see it that way.
how do you guys see it?
at that scene costello looked almost like a father figure.
I thought costello had grown to like billy and wanted billy to have a normal and safe life.
