No, I was only giving my own opinion.  I certainly don't think that Theresa has pondered it to this degree - I know I hadn't when I was that age.   But I agree with Lukkai that she's at the age to start, and (forgive the cliche) she's between a rock and a hard place - she either continues on the road she's started down, which could mean having to kill or harm another person again, or she turns her back on it, hangs up her pistol, and risks losing someone else she cares about through inaction.
There's also the fact that she ended Debby's life, which has been preying on her - of course, I don't say she killed her friend; the ones really to blame for that are those who assaulted her and caused her brain death.
My guess is that the whole "thou shalt not kill" was brought to the fore by shooting Ruby, but her feelings about Debby not being resolved play at least as large a role.
One thing's for sure - if Theresa's not just going to turn her back on everyone (or go insane), she's going to have to do a lot of growing up in a very short time.
