Let's look at what you said:
Orochimaru was dead, just like I said. Now, Kishi did something no one guessed, and it so that Sasuke could revive Orochimaru through the cursed seal. You didn't guess that, it doesn't match with your shitty theory, and you're still a dumbass douchebag.
Now that it's happened, and I've explained it, you're still wrong and clinging to your theory like a little kid.
1. The cursed seal Oro puts on people acts like a tether or a beacon for his soul when he dies, and keeps him from crossing over into the spirit realm. This way, he can always come back.
2. This has nothing to do with anything you've ever suggested. No, the soul is not different parts and he doesn't put these different parts into people.
3. When are you going to get it through your thick skull that you're a dumbass?
