This comes down to issues with the Catholic Church as whole, not the individuals.
Her actions were trying to bring benefit to the Catholic Church, which is the path to God (Brainwashed)
Someone said she "erected churches instead of housing for the poor"; which is more important in the eyes of the Church/God?
Not saying I agree with the actions of Mother Teresa, but to suggest she is the most vile liar of the past century is a bit of a stretch.
I've been going to Catholic church with my lady for the past year... it is a cult mentality for sure.
My lady's parents seem to put Church ahead of their own children 99% of the time. Quite obnoxious.
