The Twelve Kingdoms (Volume 1): Sea of Shadow

Whether she trusted others had nothing to do with whether or not she was betrayed. Whether or not others were kind to her had nothing to do with whether she was kind to them in turn. Even if she were all alone in this big, wide world, if not a single person would help her or grieve for her, that gave her no cause to play the jaded coward, to abandon those in need, to bring harm upon perfect strangers.

"Really? Truly? Being played for the fool is just peachy with you?"
"If that's what it comes down to, yes. The betrayer only betrays his cowardice. It does me no harm. But better betrayed than be the betrayer."

Is your life that precious to you?
There's no reason it shouldn't be.
You're stabbing your Good Samaritan in the back.
He didn't necessarily help me because he's good.
That doesn't change the reality of what he did. He gave you shelter and a place to hide.
He had his reasons. It wasn't out of the kindness of his heart. A person like that will betray you eventually.
So it's okay to abandon someone if their intentions aren't perfect? Do you really want to go down that road?
