Thanks so much for pointing that out to us. We must be too stupid to figure out obvious shit.
Sarcasm aside, it's not that we can't figure out why she wanted to capture him instead of kill him. It's simply the fact that the "why" is retarded. You don't let all those people die just to save one innocent girl you just met from going to prison. Itmighthave worked better if it had been Trish instead of Hope. At least there the conflict would be more acceptable. It's just shitty, lazy writing in an otherwise decent show.
