When it comes to describing someone who has a positive and kind attitude towards others, there are many synonyms that can be used instead of "having a good will toward". For example, you could say that someone is "friendly", "amiable", "affable", "approachable", "welcoming" or "hospitable". Other synonyms could include "generous", "benevolent", "compassionate", "kindhearted", "charitable", or "magnanimous". Additionally, if someone is known for their willingness to help others or to do good deeds, you could describe them as "altruistic", "philanthropic", "humanitarian", "selfless", or "noble". No matter which synonym you choose, they all convey a positive impression of someone who is genuinely good-hearted and caring.
