Being an opportunist is about taking advantage of circumstances, but being a "more opportunist" may connote a lack of scruples or ethical considerations. Some synonyms to describe this behavior include: Machiavellian, calculating, cynical, exploitative, ruthless, self-serving, sly, and unscrupulous. While these traits may help an individual advance in certain circumstances, they often come at a cost to others. Conversely, being a "less opportunist" could imply being more principled, compassionate, or values-driven. It's important to consider the impact of our actions on both ourselves and those around us, and to strive for ethical behavior in our pursuits of opportunities.
