No, no Camarro, Casilda, indeed, has a valid point and a strong argument. She quotes the following section from the Scripture of Soldeus: Sin and Virtue

It clearly states:

Truth: The Eye of Soldeus sees all and His radiant Light pierces through all lies and deceit. Those who shroud themselves in deception darken their spark and invite the dark and hateful one to tempt them further into shadow. Always in the Word of Soldeus is the truth spoken, and thus do the faithful always act with upright honesty and integrity. We must speak truth always, even in the face of danger and of the powers of the dark.
Here, Soldeus has spoken: One cannot lie under any circumstance. It would be easier to worm my way out of this one and say: "Well I didn't actually STATE that I had the money." Or I had appended my deal with: "Soldeus Willing". However, these are cop-outs. Whilst my words, to him were TECHNICALLY true, I had chosen them carefully as I was, indeed, 'shrouding myself in deception'. Thus by deception I am at fault as quoted thus:

Deceit: The most dangerous and powerful tool of Umbra is that of
Deception. He is the master of the art of concealing or distorting the truth for the purpose of misleading the Children of Soldeus, and the propagator of it. To be unfaithful to the Heavenly Father is an act of deceit and those who are false to duty or break their word are on the path to unending darkness.
This act of deceiving somebody else into obligating themselves into a trade with myself is a Sin, no doubt about this, and I thank my fellow believer, Casilda Tametoto for reminding us ALL that no Mortal is perfect, even if they are a Friar in the Church of Soldeus.

The only point I believe is weak is the implication that the people are to blame, there is no Sin upon them as they have not performed any act of deception, in fact, they have only performed acts of Virtue considering that they have donated to the construction of the Church of Soldeus.

And so as a consequence I take full responsibility for my actions as they were mine, and mine alone, and I refer to the Reverend Father Varrick ChaosWielder's judgement on any means to purge me of this Sin and if I have conducted myself in an unholy manner, or even if I have forfeited my right to even be part of the Holy Mother Church's beloved Clergy, who should be the upstanding example to all Mortals.

Soldeus is the Ultimate Forgiver
