I believe this thread started with an attempt do disprove MWI by
stating that the quantum suicider would violate the second law of
thermodynamics. Although I do believe that the MWI logically leads to
universes where the second law is violated and am fine with that, I'm
just proposing that in the case of the quantum suicider no violation
is observed at the macroscopic level. The macroscopic level is where
the second law makes sense anyway, because of its statistical nature.
I am prepared to agree that this is a pointless exercise because MWI
leads to second law violations anyway. :)
