When performing their duties as POA and commiting an offense while acting in that capacity. You cannot commit an offense using the "color" of someone else's identity any more than you can commit one under your own identity.
If you commit the crime of larceny while exercising someone's POA you may be charged with any number of offenses due to the nature of the unusual and unique power you were supposed to be executing. Depending on the circumstances of the actual offense(s) it might be one of many (e.g.: Theft - Embezzlement - Fraud - Breach of Fiduciary Duty - etc.).

You cannot make changes to a POA unless it is your own. For example, if your husband granted a POA to someone you cannot make changes in that POA.
As a wife, you typically do not have the unilateral right to change your husband's power of attorney that was given to your son in 1997. The power of attorney document can only be changed by the person who granted it, your husband in this case, if he is of sound mind and capable of making legal decisions. It is advisable to consult with a legal professional to understand the specific laws and options available in your jurisdiction.
Generally: A general POA would expire when the principal became incapacitated. If there is a durable POA that was executed when the principal was competent then someone must petition the court to be appointed the guardian. A court appointed guardianship would extinguish a durable POA.
Not necessarily. If the POA is of a limited duration, it may expire. However, a Durable POA that is not of a limited nature would continue to be effective.
There is no such thing as an irrevocable power of attorney. The principal (grantor) of the POA can revoke anything they have given someone else at any time they choose.
No. Only the principal can change a Power of Attorney. If the principal is legally incapable then the POA cannot be changed. In order for a POA to remain in effect after a person becomes incapacitated the POA must be a Durable POA. If an attorney is tampering with the POA he/she should be reported to the State Board of Bar Overseers.
The principal must revoke a POA in writing and deliver the revocation to the attorney in fact. A copy should be delivered to any facility where the POA had been used.
Price on application (POA)
The persons wishing to have the POA invalidated must follow the prescribed legal procedure according to the laws of the state in which the POA was granted. When a POA grantor dies the POA becomes invalid and the deceased's financial matters become the jurisdiction of the probate court and the executor of the estate. If no executor was named in the Will or no Will was current the probate court appoints someone to oversee the estate of the deceased.
If there was no successor named in the original POA then that POA is extinguished. If the principal no longer has the legal capacity to execute a new POA then someone must petition the court to be appointed the conservator to manage the estate and the affairs of the person who is now incapacitated.
