I think it is generally pretty hard for one individual to psychically affect another individual unless there's some kind of relationship between them with interest on both sides.

I there is always at least some degree of projection and denial on both sides, and that it is not at all easy to tell who is doing what.

I think that it is possible to actually wrong someone, we aren't perfectly protected by our own karma. Our relationships are real in that sense.

I agree that one's own bad energy recoiling on oneself is a real thing. Maybe that's most of the story of my life. I'm skeptical of the idea that the energy I put out has my identity in it though, that its ever 'mine' in some substantive sense. Yes you can feel my identity through it, but that's because the things I am doing, psychically or otherwise, are related to me. Its like if someone is spraying a hose at you, it is clear who is doing it. But the molecules of the water aren't magically imbued with their identity.

I see two things that work for long term karmic justice. One is that you can't get away from yourself, and you can't change yourself without coming to some kind of honest reckoning about what you've done. Another is that Providence doesn't forget without forgetting more than you might want it to. It knows what is connected to what - it isn't limited by time and memory.

That said, I'm skeptical about the idea of justice as a real absolute. I think that wrong can't always be altogether undone through atonement, and things can't always be worked out in a way that's ultimately fair to everyone. I think that justice is more of an aspiration, like justice in a human system of law. I also think that justice is less important than freedom, even though both are very important. I have no doubt that I'm halfway wrong about this, that I don't completely understand. But I also think that I understand as much or more than those who preach the 'truth' of perfect karmic justice. I think they're making that up, or appealing to an authority that makes it up for them.
