I was always taught that your thesis statement goes at the very end of your introduction paragraph.
[Mary Shelley’s “Frankenstein” illustrates how society has a large impact on how a person’s personality is formed. Shelley uses the creature as a tool to show the delicate transformation from an innocent being capable of love, to a hate filled self-loathing wretch. In “Frankenstein”, the creature is a personification of the human psyche when deprived of affection.]
The last sentence would be the thesis statement.
Yes, the thesis statement is what draws them into reading the whole paper, if it isn't interesting then they're just wasting their time reading it which is why it's important for you to come up with a good thesis statement and incorporate it into the paper. Come up with a good first couple sentences, write your thesis statement then make another sentence that would flow into your new paragraph.
