Ellipsis

The original text:

What, but the mystery which it obscurely typifies, has made this piece of crape so awful? When the friend shows his inmost heart to his friend; the lover to his best beloved; when man does not vainly shrink from the eye of his Creator, loathsomely treasuring up the secret of his sin; then deem me a monster, for the symbol beneath which I have lived, and die! I look around me, and, lo! on every visage a Black Veil!"

I have been given a section, and I need to correct the grammatical errors following The Chicago Manual of Style

However, Mr. Hooper cried out “What, but the mystery which it obscurely typifies, has made this piece of crape so awful? I look around me, and, lo! On every visage a black veil!”.

However, Mr. Hooper cried out, “What, but the mystery which it obscurely typifies, has made this piece of crape so awful? . . . I look around me, and, lo! On every visage a Black Veil!” (Delete period)

Are the revisions satisfactory?

Is any other correction required?

Is the ellipsis following ? in the last sentence necessary? Has the ellipsis been correctly placed?

Should bracketed ellipses be inserted in such cases?
Kindly explain.
