No, you are really not free to say something that is stated bluntly in the Tanakh. I quoted for you a verse that backed up my point. You have nothing except a new bunch of writings that contradict the original. No different than the Vedas, the Quran, the Book of Mormon.Everyone is free to read it for themselves and decide weather or not keeping the Law perfectly will bring the blessing of eternal life. As it shows in the law, if you disobey (not perfectly) you receive the curse. You may believe it is a temporary curse that is lifted immediately because you say sorry, but there has been no atonement.
What you choose to ignore is the curse, and being redeemed from the curse. This you do to your own detriment.
