Concept: This question asks for an antonym (a word opposite in meaning) for the word "ruthless."
Step 1: Understand the meaning of 'Ruthless'
"Ruthless" means having or showing no pity or compassion for others; cruel, harsh, or merciless.
A ruthless person acts without any concern for the suffering they might cause.
Step 2: Analyze the meaning of the options
(1) Brave: Having or showing courage; able to face danger or pain without fear. While a ruthless person might also be brave, "brave" is not the opposite of "ruthless."
(2) Generous: Showing a readiness to give more of something (like money or time) than is strictly necessary or expected; liberal in giving. This relates to giving, not directly to compassion or pity.
(3) Kind: Having or showing a friendly, generous, and considerate nature; showing sympathy or understanding. Kindness implies compassion and a concern for others' well-being, which is directly opposite to being ruthless (showing no pity or compassion).
(4) Cruel: Willfully causing pain or suffering to others, or feeling no concern about it. "Cruel" is a synonym for "ruthless," not an opposite.
Step 3: Identify the word opposite in meaning
The word "ruthless" implies a lack of compassion and pity, often leading to cruel actions.
The word "kind" implies having compassion, consideration, and gentleness.
Therefore, "kind" is the most direct opposite of "ruthless" among the given options. Other strong antonyms could be "merciful" or "compassionate."
