This is exactly why I cannot stand EJ. I think he wants to take down Nicole, Dan, and Rafe because they had the nerve to go against him, the "all powerful". He really won’t be concerned with the child, he was just a possession to own and show off.
I truly believe that he has no idea what the real meaning of love is. It is all about power and control. It is an added bonus that he thinks that he can get Sami away from Rafe. But it is not because Sami is his own true love, it is just to control and possess her. As usual, once he gets her, he will treat her wrong and the cycle will continue.
