I see where you're coming from, but to be succinct:
If your argument were correct, then duress would never serve as an acceptable defense.
I'm not saying that Chris was under duress (his situation was due to his own choices, not forced upon him), but the fact is, some accused criminals are able to defend their crimes by saying "my actions were necessary to avoid a serious, immediate danger in a situation that was forced upon me." That is a form of need and it is a legally workable defense, at least in the USA and UK.
