Liberty has oranges! Do you want some? On Rica, where I'm from, there were no oranges, and I grew up listening to people talk about them and how nice they were. I never thought I'd get to actually taste one.
It's not right that those people on your homeworld treated you that way, Dean.
You're an individual with your own rights too. It's wrong for anyone to use you. If they want you to fight monsters, they should make a fair contract with you, so that you're paid fairly for your work.
You don't have to help everyone, okay? Or protect them. I bet you don't like everyone on the station, right? There are some people you like a lot and you'd want to help, and others you don't like or even just don't know so well. It's okay to think about your own values, Dean. What do you want? Not other people. You.
