Deathly Hallows, he left Hermione. Poor guy.

His brother died and he heard the woman he loves get tortured.

left Hermine and his brither got killed! :(

His brother died...he left Hermione...he had the horcrux tormenting him, saying that Hermione loved Harry and not him...

That's a lot for a guy to put up with!!!

The locket put him through hell and caused him to turn into an uber jerk and leave the trio. Therefore, he went on his own personal agony trip after leaving them because he had no idea whether they were safe and I'm sure he felt horrible for the things he said to Harry and Hermione, especially to Hermione since he realizes he loves her. Furthermore, the fact that he has to listen to Hermione get tortured at Malfoy Manor while being unable to do anything until Dobby's arrival, and losing his brother Fred, the guy had it rough!! I would not want to be Ron in the last book. However, his love with Hermione is realized finally and he also kicks some major ass so woot!

His brother died!!
The locket was torturing him
He regretted leaving Hermione and Harry and couldnt come back to them until he figured out about the deluminator
Worring about what was going on with his family
Not being able to do anything to help Hermione in Malfoy manor....

I think Harry, Ron and Hermione all suffered the most in the DH :(

I agree with the previous comments!
Poor Ron!!!
His family, the battle, the anxiety, and the locket,his love for Hermione when she was in danger in the Malfoy Manner....:'(((

i agree with the previous comments too.

He lost his brother, he left Hermione and having to carry the locket around.

Got squished by the brains!!!!

-the accident with his arm after apparating
-having to carry the horcrux
-worrying about his family
-his fight with Harry
-leaving Harry & Hermione
-the horcrux saying Hermione loves Harry more and Molly wants Harry as her son rather than him
-hearing Hermione being tortured and scream in Malfoy manor
-losing his brother

I think the Goblet of Fire because:
- He fights with Harry
- He isn't getting any attention and Harry is

The Deathly Hallows is really bad for him too.

^Agreed but also DH
