Gatsby... Good or Bad?

I think that Gatsby is no doubt a good person. That doesn't take away the fact that he is selfish in his way when it comes to Daisy. I feel that he is only selfish because of his love for Daisy & desire to be with her. But taking away his selfishness, Gatsby is a good person because he has lavish parties in which HIS GUEST enjoy and use it to get away from their lives. He did a huge favor for an officer he didn't even know and when Nick told him that Daisy was going over for tea, he offered to cut Nick's grass. He didn't "have" to cut it because Nick had already arranged the meeting; Gatsby did it out of generosity and thankfulness
