I appreciate life! Life is beautiful, if bumpy and excruciating. I actually have no fear of a merciful death. I'm a little afraid of the possibility of hell existing.
Nothingness doesn't scare me, as a matter of fact I'd gladly welcome it, but millions of misfortunate souls out there deserve an infinitely better conclusion. For that reason, I absolutely loathe it!! The more I believe in it, the greater my hatred grows. Otherwise vanishing is the ultimate peace of mind.
What I'm terrified of though, is if I end up being physically taken care of by someone, be it due to illness or old age. The thought of close people dying terrifies me as well.
