Don't worry, Doc. I wouldn't call anyone who could deliver the Cruciatus Hex with a smile 'good'. Snape has his own agenda that involves Voldemort's defeat. Frankly, if he had lived that long, I would have expected him to attack Harry with lethal intent the moment Voldemort was down for the count. Such is the nature of a petty and vindictive man.
I hope we will see more of what has changed Harry so much for the better.
