I'd say it's prolly like he was hurt after what happened at school and he wanted to get back at them (which includes Aoi) so revenge here basically. But like he's good deep down and that's why he realizes his mistake and start's feeling guilty about it. Which is why when he sees her, he gets flustered and runs away. Like he wasn't really evil incarnate. The situation changed him as such.
Before she gets to complete the sentence his anxiety reaches its peak and he makes a run for it. Few seconds before the signal changes he finds himself in front of a truck while the truck driver honks.
