Every ones circumstances are different.
Question: "Do you have any family in the Borg?" If so they will cut you dead , walk past in the street and pretend they dont know you.
If you do have family , consider carefully their feelings.
If not and you really dont want to have to be doing with them any more - then do it if you want to walk away. But the other posters are right when they say that the cong will not know why , or even care why, very much . To them you will be just one of the "Evil Slave", who went away being "Not of our sort"
If it will make you feel good , do it!
JT. What do you have against elders, as we were, who have not had equivalent of a high school education?
In Britain we call that snobbish . A couple of the best men I knew in the Elder bodies were plumbers by trade , but they had perception, could read character and had love for their charges. You can't judge a book... etc
