If I could remove one immaterial bad thing from the world forever, it would be hatred. Hatred creates division between people and destroys peace in societies. Because of hatred, many conflicts and wars happen, and innocent people suffer. If hatred disappeared, people would start understanding and respecting each other regardless of culture, religion, or background. The world would become a place full of kindness, empathy, and cooperation. Removing hatred would allow humanity to grow together in harmony and build a future based on love and respect.
