Generally speaking, yes.  I would have to weigh the principles involved.  Some of these questions are just way too broad to give good answers.  Would I steal a loaf of bread to feed my starving child?  Yes.  Would I place a bomb in Grand Central Station at the request of his kidnappers?  Probably not, but I do not have a child, so who knows for certain?  Regardless, I do not have a blanket answer.
I do not believe acting on higher principles would enable me to evade the consequences of my actions.  I would sure as the world argue that vehemently, however.
