HK-47
KOTOR I
"Observation: I am a droid, master, with programming. Even if I did not enjoy killing, I would have no choice. Thankfully, I enjoy it very much."
HK-47: "Your pupil once asked me what I thought of him and I informed him of his meatbag status. He was unimpressed, but you thought the reference was humorous. You programmed me to continue using that reference. It drove your pupil to extreme lengths of frustration."
Revan: "So... Malak was the original meatbag. I like that idea."
HK-47: "Of course you do, master. You liked it then as well."
KOTOR II
"Definition: 'Love' is making a shot to the knees of a target 120 kilometers away using an Aratech sniper rifle with a tri-light scope. Statement: This definition, I am told, is subject to interpretation. Obviously, love is a matter of odds. Not many meatbags could make such a shot, and fewer would derive love from it. Yet for me, love is knowing your target, putting them in your targeting reticle, and together, achieving a singular purpose, against statistically long odds."
