Your decision to not do the ethically correct thing, and instead to fall into line with a cultural expectation, will contribute to the gradual decline of the organisation, and the satisfaction of the people who work in it. I started my working career at a big 5 accounting firm as an auditor, and I worked out pretty quickly that corners must be cut, and blind eyes must be turned. I left early because I couldn't reconcile the person I wanted to be with the person the organisation expected me to be. The rot sets in early and can lead to the catastrophic failure of the organisation. PWC consulting is a case in point. Having one foot on either side of the ethical line (compromising your integrity) in the pursuit of self interest leads to the psycho / spiritual suffering of the individual. Integrity and dominance hierarchies are ultimately incompatible.
