Can a good intention rectify a corrupt act in terms of disobeying one's parents, and how can one be delivered from this disobedience given the intense anger?

Disobeying one's parents is one of the gravest sins, and anger is not an excuse for committing it; rather, it is an ailment that must be treated by striving against the self. If that does not succeed, one can resort to psychiatrists. A good intention alone to honor one's parents is not enough; it must be coupled with good deeds, for faith is قول وعمل ونية (statement, action, and intention), and persistence in wrongdoing indicates a corrupt intention.
