There is a perverse pleasure in shunning those who are outside of Jehovah's very own earthly organization. Jehovah God himself has lovingly provided the disfellowshiping arrangement through the Governing Body.
Because the DFd ones have chosen a path that has taken them outside of the protection that the Society offers, they are wicked and deserve the shunning they receive (indeed, they are deserving of death and even much more but Jehovah being merciful, he will simply kill them at the big A for not being a part of the Magazine Publishing Empire aka the Watchtower Bible and Tract Society rather than torture them endlessly). Know that if you maintain the strictest stance toward shunning, you provide the wicked one with an exemplary display of devotion to Jehovah. Many have been brought into The Truth this way.
And if they are not, look forward to that thousand years of burying bodies followed by an eternity of petting pandas (as one JWN member here likes to say...I forget to whom this reference should be attributed). You will be richly rewarded with eternal life by obeying the GB of the WTS.
Pleasure? You bet! Hot damn, it feels good.
