You should realize how shaky your position is when you have to frequently ascribe motives to others which are not in evidence. The president expressed real emotion and that definitely, as he said, influenced his decision.
He also explained his emotional reaction when saying he could not begin removal procedures on the so-called dreamers. He used that to explain why he did not keep his promise to reverse Obama's EO on his first day in office.
Pretend whatever you want to pretend, but President Trump himself is explaining his big heart and his emotional reactions and how they have affected his decision making. He's also done that to explain some of his actions as a private citizen and businessman.
