Why your exsistence is more worthless than you previousy thought it was.

[Angrboda]

I misunderstood the OP. I thought he was literally saying something happens after you die.

As to the rest, it's nothing more than a statement of the value he places on his life. Statements of value are by nature relative, so you can't say that this specific value of an individual's existence holds absolutely and from all frames of reference. It's assuming a specific viewpoint on the question of life's value and insisting that all others must share that same viewpoint because the viewpoint itself is an objective fact. It's not. Viewpoints themselves are not objective facts, so the OP is simply wrong.
