Don't worry, Witnesses are totally and completly wrong. There is precious little about their belief system even remotely true. They lie about their opposers. They lie about people that leave their organization. They lie when they present science by totally misrepresnting the views of the scientists they (mis-)quote. They lie about their history. They lie about facts regarding their keystone years, such as 607 and 1914. They lie or deceieve subtly in connection to just about everything they teach.
And that's just their lies. They also produce a stiffling, legalistic culture where people are controlled by fear, guilt, and obligation. This affects the mental health of members in ways that will become apparent once you start reflecting on your own experiences with people in the org.
Don't worry. They're totally, totally wrong. Just do your research. Research things that you're interested in - whether those are scientific fields, psychology, history, sociology, you name it. The more you learn, the more you'll be blown away by just how incredibly wrong they are about everything.
