How much affinity does the Doctor have towards Gallifrey and its inhabitants?
I'm a little bit confused as I started watching the show in 2005 with the Eccleston era. Here is the information I have:
SPOILERS ! (duh)
Season 1: "Don't you think I want to go back and save them?"
Apparently the Doctor is missing Gallifrey and he feels alone as the unique member of his species.
Season 4, The End of Time: "They must not come back, they will bring back the Nightmare Child"
Ok now this is weird: Gallifrey is now a threat?! Sure, appearing near Earth is a threat anyway but the Doctor seems to mention a lot of elements about the Time Lords themselves.
Season 8, Death in Heaven: Missy gives the Doctor coordinates to go to Gallifrey.
We can see the Doctor going to Missy's coordinates, seeing nothing and slamming his fists on the TARDIS commands. Anger? Deception?
Season 9, Hell Bent: The Doctor arrives at Gallifrey... and stays in a peasant's house while military and high council members come to greet him.
We see later in the episode that he is troubled by the death of Clara and wants to save her, therefore triggering the prophecy about "Me" destroying Gallifrey.
So what is the purpose of the Doctor trying to reach Gallifrey?
