Could Lupin come back? Will Harry want to come back?

I was thinking about the many parallels between Harry and Remus, and 
for the sixth book, no similarity is more important than the fact 
that ****They both pose a threat to their friends**** Harry is now 
aware of why Voldemort wants to kill him, and knows also that anyone 
trying to save him is a possible target for the Death Eaters. This 
means that all of his close friends are in danger. Harry is carrying 
the weight of four dead people on his conscience. With this new 
knowledge, will Harry want to come back? In the midst of his grief, 
he has only two options available:
1. He can be sad and hide in Privet Drive
2. He can be angry and want revenge

Knowing Harry as we do, we all know which path he will choose. While 
Harry felt a hopeless sort of anger in OoP, I think that he will 
have a more focused anger in the sixth book, a pent-up energy that 
will make him work untiringly towards his goal. This is the sort of 
energy that helped Sirius escape Azkaban. It is also the thing that 
makes Snape go back to spy on the Death Eater meetings, knowing 
fully well that he may not come back alive one day.

Going back to Remus, I notice that Lupin, in spite of his many 
admirable qualities, does not have this pent-up energy (or he hides 
it well). He doesn't seem angry about the way people treat him. 
(It's possible that he simply did not want to show anger in front of 
young Harry, but in general, Lupin has shown a very calm nature) Is 
this just his personality, or has he accepted his situation with a 
quiet resignation?

Personally, I don't think Harry should just accept his own situation 
(that would ruin the plot of the story) But, currently, the prospect 
of defeating V-mort seems as bleak as werewolves gaining political 
rights. There is a terrible irony in this situation, that Lupin is 
working tirelessly to protect a society that wouldn't shed a tear if 
he died. So, I wonder, who is the most terrible monster in Harry's 
world? Is it Voldemort, or the society which he seeks to dominate? 
Why is Lupin so willing to fight one monster, but willing to just 
accept the other? 

What is the key difference between the two monsters that makes it 
acceptable for Lupin to resign from his position, but makes it 
unacceptable for Harry to run away from Hogwarts? They are both 
dangerous to their friends. Why should Harry come back to Hogwarts, 
but not Lupin?
