The senator...was a smart man who had made his way in life with a single-mindedness oblivious to any of those stumbling blocks known as conscience, sworn oaths, justice, duty...
The senator in "Les Miserables" is depicted as an intelligent individual who has navigated life with a relentless focus. His drive for success seems to overshadow any moral considerations or responsibilities that typically guide ethical behavior. This characterization highlights a troubling disconnection between ambition and a sense of right and wrong.
Victor Hugo presents this figure as a representation of how some individuals pursue their goals without regard for the principles of justice or loyalty. The senator’s single-mindedness reflects a broader critique of societal values that prioritize personal gain over moral integrity, suggesting that such an approach can lead to significant moral failings and societal issues.
