Hi Esmeralda, I was a baptised Witness for 38 years before being disfellowshipped for taking a stand against a certain elder.
What you describe is quite typical in many congregations. We call them the "Royal families" of the Watchtower. Often they are second, third or fourth generations in the 'truth'. In reality they are horrible people and will make your life hell once you are baptised. Also, you will find they are self righteous and are often driven by jealousy.
Just be entirely certain before you commit to baptism
