One of the best lessons I'm learning in my continuing exodus from JWism is to not condemn people for what they do. It's their choice. But that doesn't mean I have to approve of what people do (or don't do).
There is definitely a characteristic in our human nature that let's satisfaction develop into complacency, and complacency into hypocrisy.
No habit or quality is more easily acquired than hypocrisy, nor any thing sooner learned than to deny the sentiments of our hearts and the principle we act from: but the seeds of every passion are innate to us, and nobody comes into the world without them.
I myself lived many years as a JW in that condition. I was satisfied to have my family again (after I was reinstated), became complacent with my peaceful life, and gradually became more and more a hypocrite as I turned my mind away from the increasing evidence of the comprehensive falsity of the WTS.
Which is why more now than ever before my daily goal is to live by that principle:
"An unexamined life is not worth living."
