Jehovah's personality is explosive with no guarantees he won't blow a head gasket and destroy your ass for some petty offense.
I know the JWs claim Jehovah always keeps his word and once you get to heaven or pass the final test you got guaranteed everlasting life. But when we look in the bible Jehovah seems to kill even his worshipers over trifles, so who is to say that someday he won't get pissed off and destroy the whole human race and start all over again?
While I don't believe the bible or what the wt Corporation teaches about Jehovah personality, if what they say is true then I would much rather die than live an eternity under the whims of such a capricious Jehovah.
The reward system the bible has promoted is really terrible and not to be grasped at.
