I can logically deduce and prove to you that 1 + 1 = 0 if I start out with a faulty premise.
Logical != right.
Our premises are obviously the biggest thing that come into play when tackling this kind of "problem." Thus, I said that the responses to the OP will be largely based upon the ethics of the subject in question (ie, the premises), and from there, a whole slew of "logical" arguments can be made for doing this, that, or the other thing.
I thought Ragin' was looking for some kind of universally accepted logical way of reasoning through this situation when he asked, "What is the logical thing to do here?", and I just meant to explain that there is not just one logical (Te) thing to do (while there may be many "logical" approaches to the problem (Ti)), as the premises vary from person to person.
