On the one hand, yes, no one deserves any more sympathy for their demise than anyone else.
On the other hand, everyone dies, and it's impossible to give sympathy to everyone. Furthermore, they probably don't care whether you have sympathy for them or not. To me, logic dictates that their brain has ceased to function, and therefore they are incapable of appreciating your sympathy. Your sympathy is better directed toward those close to the deceased.
Morbid food for thought: when you die and your brain ceases to function, does it not follow logically that you immediately forget your life, that you ever existed?
Happy Tuesday, everyone.
