Circassia To Rostov

I am an agnostic type who believes in some sort of scientific reincarnation. If your consciousness arises from seemingly nothing, it would be preposterous to claim you couldn't be reborn again after death. I do not believe there is anything intrinsically special about human consciousness. I think we are just more advanced versions of other animals. Anyways, something has been troubling me as of late. I believe that due to me being reborn an infinite amount of times, one day I will experience extreme torture. I keep watching those infographics videos about being boiled alive or the brazen bull torture method, and I can't wrap my head around why a loving deity would allow this to happen. What is the purpose of putting people through torture. I keep researching the topic and reassuring myself that the pain wouldn't last long. I don't fear death or any other emotional pain. The only thing I fear insanely is extreme physical pain. Furthermore, I understand why pain is necessary in life. If you don't have pain, you can't feel pleasure. Regardless, the fact that a human can be boiled alive is extremely disturbing. Why can this exist in the grand scheme of things? What do you guys think?
