【正确答案】 D

【答案解析】推断题。题目询问作者说“in legal systems，the responsibility for revenge becomes depersonalized and dif- fused”这句话意思是________。文章第2段提到“The society assumes the responsibility for protecting individuals from violence．In cases where they cannot be protected，the society is responsible for imposing punishment．In a state controlled legal system，individuals are removed from the cycles of revenge motivated by acts of violence(社会承担保护个人免受暴力袭击的责任。如果社会保护不了个人，它会承担实施惩罚的责任。个人已被排除在由暴力行为引起的复仇圈之外)”，由此可推断，惩罚并不是由有关的个人直接实施的。因此[D]正确。
