:really...? a man kills a pregnant woman in a dui manslaughter case... one wrong act... the man is prosecuted (one right act) and found not guilty (one wrong act) and as he leaves court, the husband shoots him dead in an act of revenge (one right and one wrong act) and then he either kills himself afterwards (one wrong act) or is prosecuted (one right act) and found guilty (one right act and one wrong act)... so how many wrongs did it take to try and make something right...? how many wrongs had to occur for the right thing to happen...? see the pointlessness of trying to keep track of one set of behaviors to try and counteract another set... it's meaningless... the two wrongs don't make a right principle is a moralistic falsehood is just that... a falsehood...
That example is way off the deep end. The saying means "a wrong action is not an excuse for another, subsequent wrong action". We're not talking arithmetic - "wrongs" and "rights" don't add together. What we're talking about is the causal relationship between two immoral acts. The saying is valid.
