I love this manga! It's so very riveting! I think Kuwabara is a creature similar to a vampire (??) What he meant by nectar is blood. He is weak because he only gets blood when his "master" is home (hence the periodical deaths of random people) and he is given drugs to prevent him from getting blood crazy and going on a killing spree. His dislike of socializing is to protect others of the danger he poses. He doesn't like his "little brother" because the child is more accepting of their vicious nature than Kuwabara is (hence the kid eating the pigeon). JUST A THEORY!
