There are a set of steps by which your own sin comes to find itself inside of your brother.
1) Believe you are sinful (oops, are you sure?)
2) Grab ahold of that sin
3) Hand it over to your brother and shove it down his throat (project)
4) Disassociate yourself from it and wash your hands of it
5) Put on your 'happy face' and pretend you are innocent
6) Point a finger at the sin, which is now in your brother
7) Accuse your brother's sin of being evil, and attack it
You then see sin in your brother and seemingly 'not' in yourself, because your mask of pretend innocence HIDES the fact that the sin is still in you and never left. The face of innocence covers up your guilt and makes everyone believe you didn't do it.
The one left holding the baby is then your brother in whom you see your projected sin, and you attack him for it, to make sure it stays well away from you.
At the same time, you are then terried that your own sin, which you got rid of, might come back to haunt you. You start to suspect it's going to attack you, find you, hunt you down and enact itself upon you again.
As this is playing out, it seems to transpire that 'the sin' does indeed come back to attack you, manifested in forms of punishment and victimhood, seemingly done 'by' the person in whom you shoved your sin, and now you get to claim:
"I am an innocent victim, I did not ask for this, they are attacking me without my will, the sin is in them, look look I can see the sin in them, it's all their fault".
Well, pretty convenient, to keep up this charade, given that it conceals the sin in you, within your own mind, and puts on a show that you are not sinful at all. You're trying to convince yourself and everyone around you that you do not believe you are the sinner, all the while keeping your sin hidden in the shadows of your mind underneath your blanket of fake innocence.
Now, to reverse this is going to mean, you have to take off the fake mask of innocence, you are going to have to stop being a victim, AND - horror of all horrors - you are going to have to TAKE BACK the sin that you shoved into your brother. It's yours, anyway. You have to separate your brother from your sin, i.e. from the guilt. You have to find a way to see them as innocent and as not `owning` the sin. It's not theirs. They are not sinful.
But you don't really want to do this because if you take back your sin, lo and behold, your mask of innocence (which was a total farce) has to be taken off of yourself, and you have to come face to face again with the sin being IN YOU. You do not like the sin being in you, that's why you tried to get rid of it in the first place.
So why would anyone 'seemingly' in their right mind want to take off their lovely sheen of innocence and own up to being a sinner? It's not exactly an attractive offer.
However, until you do this you have no chance to really heal it. And there is a healing option. If you take it quickly to Holy Spirit and let Him decide whether it's true or not, he will guarantee to find you ALWAYS innocent. It's pretty easy, but you have to be open minded about ACCEPTING that it's true that you're innocent.
There is a way out of hell.
