Sabo can't be Law. He is either dead or with the revolutionaries. Besides, they don't look alike at all. Law is from North Blue, Luffy from East Blue, so I doubt that it was possible for them to meet in the past. I think he only saved Luffy out of respect and he might also have an interest in him as a rival.
