Well, I don't really agree that Winn used faith itself for evil. She used the trappings of faith for evil, but she never really understood true faith. She lost faith in the prophets long before the end of the series, and relied on her position of power and the trappings of faith, not her actual faith, to perpetrate her evil deeds.
Subtle difference there...but a difference nonetheless.
I would agree with that, Winn's faith wasn't what drove her to evil because she later admits that she had no faith. But it is the faith of others that allows the institution of the Kai to exist, and it is that faith which gives her the power to commit evil. Faith in a God is sometimes mixed up with faith in the institution based around that God, and when that happens it can lead to bad things, such as the various sex-abuse scandals that the Catholic church covered up around the world. At one point on DS9, Winn was made First Minister purely because she was Kai, and the consequences of that could have been disastrous had Kira not stopped her.
Well, I don't believe an institution (whether that be a religion, a government, a corporation, or whatever) is inherently good or evil either. IMO, it all comes down to the individuals within it...and the choices they make.
The Catholic Church itself is not a bad thing. It's nothing more than a system of beliefs, based directly on the words and actions of Christ and the apostles.
However, that is completely separate from sundry
individuals over the centuries who have perpetrated great harm...and who have been Catholics. People are people - they make mistakes, they screw up huge sometimes...and some of them are bad people - they might be predatory...they might be cruel, they might be cowards...they might be any number of bad things and they might have any number of weaknesses. But those who perpetrate great harm are responsible for that harm..and those who covered up that harm are responsible for compounding that harm.
However, that does not mean that everything that Jesus taught, and that the Catholic Church has preserved over the centuries, is null and void.
People need to be judged on their own merits, or lack thereof. The people within the institution of the Church who have done great good will be judged by God according to what they have done...and those who have done great evil will also be judged by God according to what they have done.
There must be (and is) a critical element of personal responsibility there. In fact, that itself is part of Church doctrine. Everyone is responsible for their own actions and will be judged accordingly.
It's the same with Kai Winn. She used the trappings of faith to manipulate the Bajoran people...and she ultimately suffered the consequences for that. But do her evil actions nullify the good that Sisko, the Emissary did? I don't think so, despite the fact that they were both very much a part of the Bajoran faith - indeed, the leaders of it.
I don't see the Bajoran's faith system as a bad thing. I see Kai Winn's greed and thirst for power...and the actions that flowed from that, as the bad thing.
Bad people will use anything they can to perpetrate evil - whether that be a religion, a governmental system or agency, or a position of power in a corporation. But that does not make all religions, governments and corporations bad. It only makes some people bad.
