You could be a nicer person and you know this, this is why things are being so difficult for you right now. If you want things to turn out better for you and you want to be better then all you need to do is be a better person.
Devil worship is generally something that a person resorts to when they have nothing else left. You do not worship the devil purely because you feel like he would be the best god; people generally have some sort of crippling problem that leads them down this road. For example, many people enjoy a sinful lifestyle but they do not need to turn to Satan worship because they are doing just fine as they are. You usually do not go out of your way to practice devil worship unless something really wrong is going on in your life. If this same sinful person one day was told that all of their assets were frozen and that their house was being repossessed then they might be more inclined to turn to devil worship because the devil would give them the ability to get that house back and the ability to reclaim what is theirs through his own power. These people would normally turn to god since he seems to be the better choice but because they do not want to give up their sinful lifestyle, they will likely stay where they are in terms of that. Essentially, long winded explanation aside, to dream that you are participating in devil worship does not mean that you are all of the sudden going to become a hell demon and it does not mean that you should start your life anew and dedicated to evil, it just means you are dealing with a major problem in your life that you aren’t sure how to solve and you’re going through all of the options in your mind of how to get out of it.
