An introduction paragraph on Jack’s character development needs a solid thesis statement and specific evidence.
The most important component of an introduction is a thesis statement. We need to begin with a thesis statement, even if it is not the first sentence in your essay. This is because the thesis is a road map to the essay, and tells you what you will be writing about.
Essentially, Jack develops from the choirmaster to a savage tyrant. You can write this in a thesis statement with something like this.

“I don’t know. He didn’t say. He got angry and made us tie Wilfred up.
He’s been”—he giggled excitedly—“he’s been tied for hours, waiting—” (ch 9)
Ultimately these quotes will be used as your evidence in the body of the essay, but the facts they point to will be used in your introduction.
