Before I get to my point, Hey Marina! I completely agree with you

Hey, Grey Wolf! I keep wondering WHAT makes the Unforgiveable Curses 
unforgiveable. IS there someplace in canon that states that the 
reason is that they are the only three spells that cannot be blocked? 
I recall "Moody" saying that the AK cannot be blocked but do not 
recall him saying that Crucio or Imperius cannot be blocked. Do we 
know whether there are any other spells, beside the 3 Unforgiveables, 
that cannot be blocked? 

Some other explanations have been proposed for why the Unforgiveables 
are unforgiveable. Some say, because they accomplish pretty immoral 
(your phrase) effects, but I disagree, because there are a lot of 
spells that accomplishment pretty immoral effects. 

All the other explanations hypothesise information not given in 
canon, such as, the 3 Unforgiveables damage the recipient's soul
not just hiser body. 

Or casting an Unforgiveable requires summing up a level of hate and 
arrogance (or some other set of Bad feelings) in oneself; no wizard, 
no matter how magically powerful, can cast an Unforgiveable unless 
heesh has this internal Badness. 

Or the one I sort like, that casting an Unforgiveable leaves a 
residue of Badness in the caster, so that a previously okay person 
can become as evil as Voldemort by repeatedly casting Unforgiveables.
