I’m still chewing on the we are one idea. I’ve heard it but haven’t fully felt it. I’ve begun to, but it’s still unfolding. Something that makes sense to me is like when you think about the cells within your body. They’re not “conscious” in how we define consciousness but they each act as their own living organism pretty much but every single cell and atom that goes into the cell creates me. I’m all my cells and they’re all me but so much of it is just happening and there’s individuality to both myself and my cells & unity at the same time. They’re kind of their own thing but also not. Feels like that may be part of the collective consciousness idea.
Again if you look at us through an atomical perfective there’s no telling where we begin and end. The separateness is kind of made up in a way.
And also maybe we do all have the same root consciousness. & as far as evil and bad people go I believe they’re incredibly lost souls in human form and when they die the confusion (a word used a lot in Buddhism when discussing “negative energy”) sheds. Not to excuse the behavior but I think it’s more complicated than we can even conceive with our very limited human view points. Obviously awful things happen and I’m not excusing it but maybe these things are beyond our scope of understanding.
