8 billion innocent people should die because a dictator might live longer? Including your own family members and children? This would essentially be the worst cost:benefit tradeoff ever made in human history.
You cannot think of other ways to solve societal problems that don't involve killing everyone on the planet?
"cheapens the time you have" - this is just copium. When you're enjoying a day, you are not thinking "oh geez this day is good because I'm going to fucking die." You're just enjoying the day.
Well now we have a natural cap on the amount of power and influence a horrible person can have - if we remove death from the equation there is no cap anymore.
So yea I’m willing to “kill” everyone to prevent the perpetual torment nexus becoming a reality.
