It might not seem so to you, but perhaps it did to him. Maybe, in his mindset, it was his way of leaving his mark upon the world. Or perhaps, since his behavior suggests that he was empty inside, he felt it necessary to see how many people he was able to kill before the police came to get him. Maybe it was a way of testing his worth. Or, as MF said, perhaps those people shunned and/or bullied him, and he felt he needed to get his revenge. There are countless scenarios that could be formualted in order to explain why he would do such a thing. None of them, however, suggest that he was the least bit stupid. Conscienceless, yes, but not stupid.
