“Yes, if only I were like you, devoid of human sentiment.”
Now this! This is how you do a movie about an assassin! A heartless, emotionless, cold-blooded killer with no sympathy and feels no compassion for anyone, and only speaks when necessary. It’s all about the job and finishing it. None of that, “Romantic interest who reminds him what it’s like to be human again” bullshit is present here. Tackling the themes of emotions (or lack thereof) and the things they can cause us do, and the destruction they cause.
