Not true in the slightest, if you disrespect someone during life openly and are truthful about it, disrespecting them when they are thus deceased is a far more respectable feat than being a two-bit hypocrite and jumping on the "lets pretend we care" bandwagon.
death sucks wen its someone i know, why the fuck should i care about someone i never met? i see no one whines about the others 2983642938 that died/murderer/accident in the same day fucking hypocrisy
I agree that when you're dead, its not like it matters if someone disrespects you or not. Respecting the dead is more out of respect for the families who have obviously suffered a great and disheartening loss. Not like any of the Ledger clan are lurking around on COBOT, but still, you know what I mean.
