Goku hung up the phone and swept the back of his hand against his wet cheeks. He just couldn't risk it, now that he knew the truth. Couldn't risk working, being around people. Being around Sanzo. What if he were hurt someone? He already knew he was capable of it.
What if he were to hurt Sanzo?
He'd spent several hours visiting with Hakkai and Gojyo yesterday, discussing their guesses about what was going on with him. They'd told him about all of their experiences with his demon-self, and he had to admit that most of them weren't very good. If he was capable of nearly killing his closest friends back then, what was to stop him now?
Goku clenched his teeth, unable to stop the tears from continuing to slip down his cheeks. His world had been torn apart. He couldn't believe now that he'd wanted to know the truth so badly. He'd give anything to go back to being oblivious, to just be able to forget everything and go back to normal.
But it wasn't a possibility for him, even if he could do it. He'd been right, he was just too dangerous to be around other people. Gojyo and Hakkai had been certain they could help him to control himself, but to Goku, the chance was just too great. He couldn't count on EVENTUALLY being able to stop hurting people.
He had to finish what his parents had started, and lock himself away from the world.
