I am so sorry for your loss and for the dissension that has erupted.  Your brother is generally correct: he as the executor of the estate has the right to make decisions that are in the best interest of the estate in order to fulfill the wishes of your Father.  So if he has to sell assets to pay off debt then he can indeed do that.  He is not, however, a dictator and you are not without rights.  If you believe that he is doing something for spite or against the intention of your Father then you have the right to question it through the probate court.  But I would hire an attorney to review the matter fully.  Good luck.
