The accounts of the saints would disagree with you, as would the Church.
We certainly cannot understand that decision, but we know that Hell is a free will choice of the individual, as well as a punishment of God. God does not will that anyone be damned, but if that is what we chose through rejection of Him, that decision will be honored.
It’s not a pleasant thought, but then, Hell isn’t pleasant, and thoughts of it aren’t meant to be pleasant. You’re rejection of these Truths is based on the fact that you, personally, cannot accept it. I’m sorry, but that is a poor basis for rejection.
Incidentally, you are correct, I’ve never read a description of the souls walking into Hell. They run, they flee from the presence of God. At least one account say that this is because being close to Him pains them more than the fires of Hell.
This is all I have time for today. I encourage you to read the Catechism, and seek out the accounts of the saints. They are very enlightening.
