If P then Q, P therefore Q. Q is not the conclusion, it's just the consequent. If P is false, then Q could be true, but claiming Q is true because P is true when P is actually false is a wrong conclusion.
take something you know to be true. now come up with a stupid, falacious argument for it. now you can see that seeing an argument is bad doesn't mean the conclusion is wrong.
