Only the hurt and the corrupt and the degenerate and the broken and the perverted and the addicted and the depressed and the hating ones know the true pain of heaven. Easy for a natural saint to say that they had to give up evil. For they know not the many-layered excellence of it. It is excellent to be in the momentary satisfaction of evil even though always evil results in horror. Hell is pain. But hell has a clear and forceful value.

It is a fact that we are in complete control of our actions and mental state. It is also a fact that we are not: for establishing actions and repeating them binds you to them. It is finally a fact that we are created with certain dispositions as follow from some innate unchangeable traits.

Thus as the evil grows deeper, as the mental state and the emotional system set up around the evil become more entrenched and as one perfects it, it becomes a greater struggle to end the cycle of acting it. All personal evil is an enacted reality that is chosen, and thus all evil is an act of universal construction. It is possible then to end up in a very dark universe, or at least a universe that has a very dark pocket in it.

But it is utterly painful as well to turn from it. There are problems and benefits less manifest than the obvious pains and pleasures inherent in an evil cycle. The first is that by the nature of the evil reality having entrenched itself, it is accessible to serve whatever purpose it serves for the enacter. To stop doing something that one has been doing in some form for years, maybe their entire lives, isn't just hard, it is naturally terrifying. When we turn from a set of actions that were producing some results, we have to give up on one of our tools to produce said results. As if a warrior was forced to lay down a sword against an unarmed opponent. The warrior knows that they should fight with their fists, but it is logically frightening to put down the sword. With most evil cycles there are elements of being, and chemicals in the mind, that are produced in predictable and amplifiable ways by its doing. The evil is a response to stimuli that plays out along the lines of producing these realities. These realities are safe, they are also clear and vicious.

Heaven by contrast is subtle. True happiness disperses energy across a broader range of the self than evil, it stretches across the mind and softens all things. But by that nature it is hard to hold. Things that produce goodness today may not produce goodness tomorrow, aside from the great tasks such as art, business, god, and love. By contrast evil always produces its sharp and specific result. Always. The drug makes you feel something focused, or the violence, or the hatred, or the perversion, they all have a direct result. To give up that directness, that tactile capability, is a concerning prospect.

Creativity, introspection, prayer, compassion, industriousness, and love are all a great deal more fickle than heroin.

Ultimately the old axioms upon which the most primal advice about life rest are the best way to cut to the core of the argument to turn from evil and to bare the burden the pain of the uncertainty of heaven. For when one deals with the knowledge of God's fruit, there is a depth of import that brings us to our basic analysis of reality. 

To continue to conduct evil is to end up in hell. 
To be good is to end up in heaven.

But heaven and hell are not the eternity of the hereafter. That would be far too easy. Heaven and hell are the eternity of the now. They are the precious moment ruined and perverted or loved and perfected, every moment stretching on and condensing down and piling up, the lived actual universe that your eyes see and that other people are affected by. We tremble then, the stakes are very high. The stakes are every single thing you have to experience until the day you die.

And it becomes clear that as you feared,

Within you rages the war for the soul of the universe.
