But he has Henry, his one and only blood relative, who just might be willing to give his grandfather a second (third/fourth/fifth...) chance. I am not so sure of that, considering Rumple tried to kill Henry on several occasions.

Then there is everything that happened during the 4.b arc, especially the finale, that may cause Henry to never forgive his paternal grandfather. Rumple tried to turn Emma into a villain, and took away everyone's free-will. He attacked Henry in the AU, and almost killed Regina.
