A purpose-oriented person is usually ambitious and believes the end goal is all that matters, not the path to get there. They believe it is right to abandon established principles if it is in the service of achieving important tasks, projects, or goals.
In the workplace, they prefer not to work with people too principled and are able to break promises in the pursuit of success. They exhibit loyalty only while it is useful to them and as long as it serves a purpose. In those circumstances, they can act loyal but are generally more flexible to achieve their goals.
This can often be through self-interest and the determination to perform or achieve success. They believe reaching goals is enough evidence of their success and if a few people are let down in the process that is life and necessary to achieve that success.
