I hope this helps, Jesseka,
You might have heard people talking about “death” like a catepillar’s cacoon. For instance, a Catepillar fills itself with so much food, tree leaves, then it Metamorphosis into a cacoon breaking its own body or skin and attaching itself onto a leaf, fence, and etcetera.
Consequently, this parable or image is wholesome a good way of describing the death of human beings, since we do not die, we are only metamorphosing, dying to our bodies or, lets call it, dying to our cacoons and hatching ourselves into the spiritual realm. We know that the catepillar will cease to be a catepillar upon receiving its wings. In other words, when the catepillar transforms itself into a colorful butterfly flying around.
Also what we have to focus on, is not so much the images of hell, but the reason why mortal sin separates us from God. This is more important. Here’s a good example: If this is so, that once a person has died they receive a greater awareness of reality, which means, our human brains function around 10% while living on this earth and the other 90 % does nothing. Then upon death a person has a fully matured conscious or awareness at work. Which means that our spirit, our consciousness, our awareness, is functioning for our-very-selves 100 %, not 10%. Well, we begin to see the colors we never saw before death, we begin to see perhaps even radio waves, we even begin to be very very intuitive to the things around us, knowing even the events of the world around us even after death. We have become spiritual because we are spirits. Which means, we do not need to ask why this or why that, because we have become a pure spirit, we’re intuitive, knowing things to its full capacity, since we no longer have an impediment, an obsticle to our consciousness, awarenesses, since we’re nothing but pure spirits.
If this is so, that, once a we have died we wil receive a greater awareness of reality, a greater conscioiusness, or a greater intuitiveness. Thus, in the case of Mortal Sin if at work in the consciousness, in the awareness, while on earth, then it will fix itself in the person, in the soul, it will be a fixed evil or a fixation with evil that has sprouted in the soul, poisoning the consciousness, the soul, to become evil itself, or, better yet, another devil.
Think of it like this, “What you sow will sprout.” Therefore, what we sow in the spirit or, if mortal sin is sown in our spirit, our soul, so, upon death and because we will receive a greater consciousness or a greater awarenesses after death, a greater intuitiveness. Well then, what mortal sin does to us is give us a greater awareness, a greater consciousness, or better yet, the knowledge of evil, an intuitiveness to do evil and know evil. Therefore we begin to be even worse than before. About this Jesus tells us, “To whom is given more, and more will be given to him. But to the one who thinks he has, even that what he thinks he has will be taken away from him.” In other words, their state becomes a lot worse than before, since it is evil itself at work within the soul that has taken over or killed the intuitiveness to love, to do charity, and to be kind. Likewise the soul cannot love anymore because mortal sin, “not venial sin” has killed off love, charity, or the grace of God.
It’s all about consciousness. It’s all about knowing that after death we are given or we will enter into the state of supernatural awareness, consciousness, or a supernatural intuitiveness. So, it is the intuitiveness to do evil while living on this earth which grows and sprouts into something so poisoness, that the person - man or woman - become exactly another devil, a fallen angel after death. As scripture says, “What you sow is what you will reap.” So if somebody sows mortal sin, then, this will grow inside of a person after death, giving them a greater awareness or consciousness to do even more evil. This is where a person ceases to be a person and now has become another devil himself. This is why Jesus said about Judas Iscariot. “Better for that man to never have been born,” since he has become another devil himself. (Read John 6:70-71)
