I doubt that science will help you...
That is the domain of faith... I see nothing in the concept of quantum entanglement that is any way relavent to the topic...
I am not an expert in any way on this matter, but it seems to me that maybe one of the first steps in your quest would be to start judging people by qualities other than skin color... maybe having empathy for other human being's suffering despite the fact that they have more melanin in their epidermis...
If you cannot see beyond the surface of skin, how can you possibly hope to approach the 'soul'?
Just a thought...
