I agree with Summer-I feel that any person, addict or not, if someone is going out of their way on a daily basis to either mentally or physically abuse another person, there are serious underlying issues there and they are releasing these issues through putting others down. I feel like I am in general a happy person and I don't think I've ever woken up one morning and said "Who can I beat down today"....I agree that addictions can be a side effect of something deeper, just as abuse is a symptom of something much deeper.
