@mirp448 - compulsive behavior is a common problem for people on the autism spectrum. I have read it is somehow different from OCD, but I did not really understood that part.
@ZeonII - people with Asperger's syndrome have problems with
perceiving other people's emotions. They are fully capable of compassion when they are aware of the other person's feelings. Of course, it does not prevent a specific person from hating dogs and wanting to kick them.
By the way, it's way easier to perceive other people's emotions in a stylized manga language than with real people or in "realistic" manga like this one.
