In conversation with an old JW friend today, it struck me that most JWs have replaced their personal conscience with a collective one.
Instead of training their own mental powers to distinguish right from wrong, as the Bible encourages, they are content to shift personal accountability away from themselves and onto the impersonal Org. Whatever behaviour may prompt an ordinary person to have serious misgivings ( such as ignoring glaring misapplication of scripture or rejecting basic human decency in favour of unchristian shunning ) they prefer to have those decisions made for them.
History teaches us, however, that there is no absolution for people who behave unethically or cruelly by allowing the excuse of 'obeying orders' to override what their inner voice should scream is inherently wrong.
