I'm not 100% sure, but there's a high chance that it is. He could've been mentally unstable already from his parents' deaths, but then, he was the "Nonexistent One", so to prove that he existed, he pushed the Teacher lady into the river. And when he smiles, it may be because he realizes that Mei is acknowledging his existence. Then, he hung himself out of guilt. Or maybe he just went insane. If you're mentally unstable already, and you kill a teacher, you'd probably just lose your mind completely.
