Eternal damnation is....

To actually do the blasphemy of blasphemies, you have to have every being in existence hate you forever. This is compoundedly more difficult, as you can always ask for a new heart, which of course will change everything about your trajectory when you seek a heart that will be adored. Now you know what it is.

I would think that it is physically impossible to get the dead to hate you forever
Also blasphemy is a religious word so has zero meaning for me as a non believer
