No, I never realized it when I was preaching. When I started having real doubts, I never went in service again.
I do feel bad that in all the years I was a JW, I did bring two people in. I haven't seen either one in years, but I know from my family that both are active at this time (both are elders).
One of them though was a mess of drugs and crime when I first found him. Not sure if he's better off or not right now but possibly it might have actually been good for him (that's hard to say). The other was a friend from high school. I think he would have done just find if I would have left him alone (didn't preach to him).
Fortuanately, most people at the doors just wanted me to go away.
