I am not sure about anywhere else, but in SoCal "decent" and "idiot" are all-to-frequently interchangeable. I can't tell you how often I get angry with myself for doing a "right thing" that I know few others around here would do. I have come to tolerate the fact that a kind deed will usually make me end up on the losing end.
Now let's look at this situation (and this is information only, it is not my place nor intent to chastise). The truth is that you did not do Everette any favors. You chose not to steal from him (and that is good), but you did not give him anything that he did not already have (in this case...a chance to get a T.I.E. Interceptor). You had no claim to that particular peice save for through a dishonest act. I am glad you made the right choice, but that particular choice doesn't bring you up on the "Goodpersonometer". But you do get to stay at the same level, it doesn't bring you down on the scale either.
This opinion is based largely on my own belief that values in general are moving away from good deeds being a matter of course. Now we all (me included) feel that we are owed a debt of gratitude if we do something nice for someone.
