What is abysmal for one, may be matter of fact for another.
Clearly, none of us can PROVE/VERIFY that they wander as ghosts, or go to heaven, or hell (until we ourselves reach that stage).
In that regard, there is zero religious/philosophical/scientific difference between you and that OP.
The only difference is that OP is quoting a scripture which states X.
If you are able to quote a scripture that states Y instead, or X except in cases of Z, feel free to do so.
If you find X abysmal, you are, in essence, finding that scripture abysmal. And it's natural to feel that way because it is natural to confuse righteous punishment with unrighteous tyranny. The only guiding light to differentiate which is which, is Shastras.
