What did dr jekyll do about his faults and irregularities

"And indeed the worst of my faults was a certain impatient gaiety of disposition, such as has made the happiness of many, but such as I found it hard to reconcile with my imperious desire to carry my head high, and wear a more than commonly grave countenance before the public. Hence it came about that I concealed my pleasures; and that when I reached years of reflection, and began to look round me and take stock of my progress and position in the world, I stood already committed to a profound duplicity of me. Many a man would have even blazoned such irregularities as I was guilty of; but from the high views that I had set before me, I regarded and hid them with an almost morbid sense of shame. It was thus rather the exacting nature of my aspirations than any particular degradation in my faults, that made me what I was, and, with even a deeper trench than in the majority of men, severed in me those provinces of good and ill which divide and compound man's dual nature."

I think that's the point of the story. Dr. Jekyll was tired of leading the restrictive Victorian life as a gentleman, He felt that "the worst of my faults was a certain impatient gaiety of disposition". Jekyll wanted to let lose; he wanted to indulge in his dark side that he, and other men, keep repressed and at bay. Mr. Hyde is the alter-ego to the mild mannered proper Dr. Jekyll.
