That is the control aspect of the JW's. You friend needs to seek out a support group and read some self help books on how to build up his self esteem. Most JW's are approval seeking and have what they call codependent personalities. That is why cults look for these types of people because they are easier to control. Codependents are looking for approval fronm others. Your freind has to build up his self esteem and not look toward any man made organization for approval.
