Suo chose this moment to leave on purpose. Sakura finally opening up about his past and fully accepted himself as part of the town was the catalyst for this decision. He knows Sakura will come for him. He knows he will have to fight him with everything he's got. But most importantly he knows that Sakura, who has now let go of the pain in his past and has embraced the strength of his friends in addition to his own, WILL NOT LOSE! He knows his friends will save him from his past, no matter what.
