Seriously how can people still claim that he is dead, we argued about this a hundred times already... get your facts straight people. Won't bother to include any arguments, just do some research. :s
1.: deprived of life : no longer alive.
2. Apperance of death.
3. Very tired
4. Lacking power or effect.
Im sure vanishing into a crap-ton of atoms qualifies him to that "dead" category. He is dead as dead could be whether he is force ghost capable of coming back to life like the emperor. He is dead unti he makes a physical apperance in physical form.
