The fact that you're asking this question tells us you have nagging doubts. Now is the best time to address your concerns, because if you become a Jehovah's Witness, leaving the organization is never easy.
Some Watchtower doctrines are very attractive and that's why people join. If it was all bad, no one would be interested. There needs to be some 'honey' to attract new members. There are pros and cons of joining the Jehovah's Witnesses.
The biggest concern people have with the Jehovah's Witnesses is that even though it's easy it get in, it can be very hard to get out. When you join most other religions, you can leave at anytime without concerns about losing close friends and family members. With the Jehovah's Witnesses, members are shunned and even hated  if they decide to leave the organization.
Notice in the above video that 'apostates', Jehovah, and even Jesus is blamed for breaking up families. The only party that does not accept responsibility is the Watchtower. This is interesting because JW's shun members who leave because it is required by the Watchtower. Former JW's, Jehovah, and Jesus can't stop the Watchtower from breaking up families and friendships. Only the Watchtower can do that.
