How would you describe Douglass’s emotions towards Mrs. Auld?

When Douglass first went to live with the Aulds, Mrs. Auld was kind and generous with her time.

Very soon after I went to live with Mr. and Mrs. Auld, she very kindly commenced to teach me the A, B, C. After I had learned this, she assisted me in learning to spell words of three or four letters.

After her husband forbid her to teach Douglass, Mrs. Auld began to change. As time went on, slavery poisoned her mind.

But, alas! this kind heart had but a short time to remain such. The fatal poison of irresponsible power was already in her hands, and soon commenced its infernal work. That cheerful eye, under the influence of slavery, soon became red with rage; that voice, made all of sweet accord, changed to one of harsh and horrid discord; and that angelic face gave place to that of a demon.

Thus, we can see that Douglass took to the woman at first and liked her for her kindness. In the end, he envisioned her as a devil.
