The person who takes every opportunity to "pick on" others is often mistakenly called "sadistic". In reality, this person is a misdirected masochist who is working towards his own "destruction". The reason a person viciously strikes out is because they are afraid of what something represents, or are resentful of happiness. They are weak, insecure, and on extremely shaky ground when you throw your curse, and they make ideal human sacrifices.
