"One can translate all they want from the original texts, but if one interprets it incorrectly, how can one be correct?"

If you intrepret something incorrectly, you can't, by definition be correct. But I would be interested to know what differences in interpretation you've found in the New Testament. And while the Old Testament of the Catholic Bible includes some of the additional books added to the Septaugent translation of the Hebrew Bible, I don't believe there are differences in translation with the books the Catholic Bible and Protestant Bible share.

The New World Translation used by the Watchtower Society translates/interprets John 1 to say that Christ was "a god", lesser than the Father. They interpret many other verses differently in order to come to a similar conclusion about Christ. They also interpret the Bible to say that the Holy Spirit is only a "life force" and not an actual person. This supports their Unitarian beliefs.

You can of course say, "Well they aren't real Christians." They'd disagree with you. Orthodoxy is in the eye of the beholder.
