When someone voluntarily wishes to become a 'man of the cloth' in the Catholic faith, he has to renounce his worldly life and desire. It is not that overnight one can become a priest, The Church spends great time and money to educated the person in formal education as also in theology. Many poor people join the Church just to get an education, good and nourishing food and a better life. This man seems to be one of those types who wanted to use the Church to his advantage and then quit, having gained the bounties of the Church. I don't think the man is mentally sick, I think he is a very clever snake oil salesman and a charlatan. The world is full of such conmen, tricksters and basic scoundrels who want to get the best of society and give nothing back in return. However, what was done to him may not be legally correct and above board.
