This isn't an answer. There's nothing italicized
I believe everyone is inherently good, but bad circumstances can turn someone evil. For example, in Lord of the Flies Jack was nice at the beginning, but because he wanted to be leader he turned evil. Everyone is always good from the beginning but everything can change just from one circumstance.
The three lines that use iambic trimeter are:
1. 'to war and arms I fly'
2. 'the first foe in the field'
3. 'that from the nunnery'
Hope this answer helps you:)!
