It could be a doubter, or it could be a true believer. Sometimes the staunchest of true believers can innocently word things in a way that resembles a skeptic, because their true belief blinds them to the fact that what they say could appear subversive. If someone really, truly believes in Watchtower 100%, then it could make logical sense to make “charitable” comments about apostates because they are lost souls. If he 100% believes in Watchtower then he genuinely doesn’t view apostates as a threat to his own belief, just misguided people.
Most JWs don’t seem to fall into this category, however, because most JWs carry some doubts around with them. And most harbour at least some suspicion that apostates may endanger their faith if given the opportunity, and are therefore not inclined to be charitable or open toward them.
