It matters, because if this all doesn't make sense, then this God probably isn't real and was created by iron-age, uneducated men who didn't think it through. So bottom line, regardless of free will, God creates people fully knowing he is going to send them to Hell...a Hell that he created. So all this clearly says that God is evil. That is why it matters. Again....God creates people to send to Hell.
"Does not the potter have power over the clay, from the same lump to make one vessel for honor and another for dishonor? What if God, wanting to show His wrath and to make His power known, endured with much longsuffering the vessels of wrath prepared for destruction, and that He might make known the riches of His glory on the vessels of mercy, which He had prepared beforehand for glory,"
Now it is up to you, freewill creature, are you a vessel of wrath or mercy?
