"More iron-hearted" is a phrase used to describe an individual who possesses an exceptionally tough, unyielding, and unsympathetic nature or demeanor. It implies that the person is cold, relentless, and unfeeling, exhibiting little or no compassion or empathy towards others.
The term "iron-hearted" combines two key elements: the strength and hardness associated with iron, and the emotional or compassionate aspect of the heart. The adjective "iron" symbolizes a rigid and durable material, often linked to strength, toughness, or sternness. In this context, it signifies an individual who possesses an unyielding and impenetrable emotional state, devoid of sentimentality and compassion.
By adding the word "more" to the phrase, it suggests a heightened level of these characteristics compared to others. The individual being described is noticeably more hardened and unsympathetic than the general population, going beyond the average threshold of emotional detachment.
Overall, "more iron-hearted" refers to a person deeply entrenched in their emotional resilience, displaying little concern for the feelings or suffering of others. It highlights a personality trait characterized by an uncompromising and tough nature, unresponsive to appeals for empathy or understanding.
