Faith is basically a ' wanting to believe ' this in itself is not always a virtue or vice.
A founded faith ie a belief or hope that an outcome will be to ones satisfaction is very prevelent in us all.
That is evidence or known circumstances should result in the desired outcome although never guaranteed.
Then there is faith unfounded but only as a need or wanting to believe even coerced through fear of judgement or punishment.
This type of faith can be either virtuous or a vice entirely depending on ones point of view.
This type of faith always has reasoning as to why the person needs it. Its coming to terms with this type of faith which a person finds very difficult as it presents a situatuon which can lead to trauma and a whole new appraisal of the purpose of their being.
I am speaking from experience, but confronting my faith and realising it was baseless has given me a happier life, not only for me but my children have benefited immensely from being frree thinkers and not bound by blind faith.
Best wishes.
