What you are saying is the following: suppose I want to prove statement T is false. I say well suppose it is true. Then I derive a contradiction. Now just as I conclude that T is thus false, you say: "wait, you have to keep in mind that T might be false afterwards..." This is not how proof by contradiction works.
