Some language can cause emotional reactions in readers. Lines like "Castrated, broken, a thing wronged,
Strapped and buckled, its hell prolonged," are impactful because they use words which the audience can't help but have an emotional reaction to. These phrases create feelings of pity and sympathy. If you think you have spotted some emotional language, ask yourself if those words could provoke a reaction in person who hasn't studied the poem as much as you have.
