Different people are going to judge what you did differently.
I can well understand the pain the JWs have caused and the frustration you feel.. My issues with these fools are their hypocrisy and selective memory loss. Witnesses don’t care who was damaged by the religion’s teachings!! Even though some people here feel ‘sorry’ for them as victims, I cannot - especially at this point.
I won’t approach them though. However, if they came knocking at my door then I’ll say whatever is on my mind. I’d tell them I know about all the changes in the religion; how they are constantly asking for money and as somebody who was criticized for my job they’d never get anything from me!
As long as you’re not doing anything threatening or illegal that’s fine. They are peddling crap and wasting time. They have to know this at some level.
