help me to translate a sentence
The excessive exercise of authority tends to invite excessive rule breaking and thus several serves to provoke the very impulses against which it guards.
答
前半句一楼译得对,“滥用权威或权力会导致对规则的肆意破坏”
后半句是：“由此有时候恰恰会激起挑战它(指权威)所要维护的东西的冲动.”
所以整句话的理解是：
滥用权威或权力会导致对规则的肆意破坏,反而会激起破坏的冲动,而要破坏的恰恰是权力或权威所要维护的.
