Dan manufactured a problem and then manufactured its solution. Dan was unable to think of any apt penalty other than "lose salvation", so he concluded that God Almighty can't come up with one, either, and so he added that opinion to the relevant verses. God promised eternal life and incorruptible seed- but He didn't promise that those who prey on others (for example) won't face an appropriate penalty that doesn't involve revoking the above. I think it's actually kinda scary that God Almighty can come up with a punishment that fits all of that at the same time. Then again, in science fiction, that could have dramatic consequences (like eternal life without adding agelessness, so 500 years later, one looks 500 years old and so on. ) I don't think that's what they'll face- but they might prefer that to what's actually prepared and kept hidden for now.
