兩件錯誤不能使一件事變得正確？

看完電影“完美無缺”，其中一段對話令人深省。男主人公盜竊珠寶以報複害死愛妻的人，女主人公勸告他說是一旦被抓會做一輩子監獄，並且也無法挽回失去的。男主人卻堅定不移，說道：
“那句俗話怎麽說的？兩件錯誤不能使一件事變得正確？毫無道理！有些時候，為了使事情變得正確，你不得不作同樣錯誤的事。代價麽？判我一百次終生監禁都值得！”

"What's that old phrase about two wrongs a right do not make? That's nonsense! Sometime to make something right you have to do something just as wrong. ...oh yes, my cost it's worth 100 life times in jail."--- Mr. Hobbs (from movie "Flawless")
